Wireless Wearable ECG, Vital Monitoring System Released in Japan

Nikkei's Tech-On! is reporting that WIN Human Recorder, a Japanese firm, has released a new body sensor and wireless reporting platform for continuous monitoring of patient vitals. The 7 gram HRS-I device seems to be a two lead electrocardiograph with a thermometer and an accelerometer as an activity sensor. All this is linked to a 2.4GHz wireless transmitter that communicates with a mobile phone or a computer, and it all can be continuously powered for three days by a watch battery. Unfortunately, Tech-On!'s report seems to be the only source of information about the device and no more details are available. We'll be on the lookout for anything else we can discover about the HRS-I.

Thermahelm Motorcycle Helmet Cools Head Upon Impact

A University of Edinburgh PhD student from the United Kingdom has created a motorcycle helmet that uses an endothermic chemical reaction to self-cool upon impact. The company, Termahelm, will soon offer the ability to either buy a helmet directly from them or retrofit your current helmet with the cooling technology.

The website is misleading on the benefit of this technology in that it points to a multitude of studies investigating systemic hypothermia in the treatment of traumatic brain injury (TBI) where the entire patient is cooled for an extended period of time. That's not what the helmet is doing and even if it were, whether or not this actually helps seems to still be an open question (see review). Also, the premise of the idea rests upon two assumptions: one, that prophylactic local hypothermia (icin' the noggin') leads to better severe head trauma outcomes. And two, that applying this therapy immediately, even before an ambulance arrives, has a clinical benefit.

That being said, it seems like a neat idea and leaves us with the obvious question: Can you activate it while riding on a hot summer day?

Toumaz Sensium Digital Plaster Goes on Trial

Toumaz Technology out of Abingdon, UK has announced it partnered with the Imperial College London to perform a clinical trial on the company's "Digital Plaster" vital signs monitor. The technology, which we covered in the past (see flashbacks below), allows for continuous monitoring and wireless transmission of temperature, heart and respiratory rates to help speed up workflow and get rid of some of the cables.

The focus of the trial will be to verify that the physiological data acquired by the digital plaster system within a clinical setting is equivalent to that acquired using current gold-standard monitors in use in hospitals – equipment that is often bulky, expensive and fixed, such that patient mobility is impaired. The Sensium digital plaster is wireless and unobtrusive, meaning that patients can remain ambulatory in hospital while still being monitored. This flexibility allows continuous vital sign monitoring to be extended to patients who would not normally be monitored, thereby offering the potential to increase patient safety. The Sensium digital plaster is a disposable device with a working lifetime of several days, after which the plaster is disposed of in the appropriate waste receptacle.

The trial is being conducted in three phases, an initial phase with non-patient volunteers followed by two patient study groups: patients recovering from surgery, and patients with specific medical conditions in the general wards.

The Sensium digital plaster is targeted for use in clinical monitoring applications such as acute care, general ward environments, tele-care, chronic disease monitoring, and in care home settings. For all these applications, disposability provides convenience, simplicity and patient comfort while ensuring infection control is maintained to the highest standards. Powered by thin batteries, body-worn Sensium-enabled monitors deliver clinical-quality data and intelligently integrate it into an electronic medical record via a network built on Toumaz’s power-optimised wireless operating and networking system, Nano Sensor Protocol (NSP).

Fitbit Tracks Your Movement Day and Night

Fitbit, a small device designed to track your every physical move, is now for sale after a year of hype and development. Fitbit clips onto your clothing and, using a 3D motion sensor, passively tracks how many calories you burn, your patterns of physical activity, and even how much sleep you get at night. Every time you're in range of the Fitbit base station, it automatically uploads your data and syncs with your computer. The idea is that you can then log in to Fitbit.com to monitor your data, set activity goals, input food intake, look at your activity trends over time, etc. The battery in Fitbit lasts ten days between charges so you can pretty much keep Fitbit by your side at all times.

Head to the Fitbit blog for more details about the product development, manufacturing, and even an explanation about how the algorithms work that track your movement...

The Access: Inclusive Fitness Equipment

The James Dyson Awards have introduced this year a "People's Choice" component of the judging process to determine the best in contemporary design. One of the entries we found interesting is The Access, an exercise machine designed for people with and without disabilities to work out the upper body. The features include push button weight selection, adjustable arms for different size people to get proper leverage, and controls that require little manual dexterity.

Here's a description from the contest entry:

The Access is universal fitness equipment that accommodates those with various disabilities and able-bodied users alike. It bridges the gap between segregated users and provides an equal platform of fitness for all. Comprised of a central tower with two arms extending laterally, each arm rotates 180 degrees independently. Additionally, each arm contains a cart that travels the length of the arm. This configuration allows any user, regardless of their size, shape, or mobility levels to achieve a personalized workout catered to their body type. No longer does the user adapt to the equipment, but the equipment adapts to its user. The Access provides an non intimidating, seamless interaction between user and machine. No longer does the user need to pull pins, pinch fingers, and contort their body in awkward positions. All of the touch points are designed in which even the most limited user, an incomplete quadriplegic, can perform an independent workout with ease.

Avalanche Safety System to Help Extend Survival Time

One of the entries submitted to the Dyson Design Awards for consideration is the AvaJacket, a safety vest to help skiers survive a meeting with an avalanche. It features airbags that open up to restrain the head from being twisted into dangerous positions, and a breathing system that aims to separate exhaled air from the much needed oxygen rich variety.

From the submission to the award contest:

The device works by extracting the mouthpiece from its pocket: in just a few seconds, the airbag located in the collar is inflated around the neck of the victim, protecting a vital part of the body and decreasing the burial depth. Once submerged by the snow, the airbag slowly deflates; with its volume, around which the snow has become thick and solid, it has gained space around the victim's neck and kept the airways clear, besides having given more chances to the victim's motion and wiggle. Meanwhile, it is possible to breathe through the mouthpiece which separates the inhaled air from the exhaled air.

New Fabric Aims to Detect High Body Temperature in Children

Being able to detect when a child's temperature rises above 37°C would be a welcome ability for worried parents. The same could be said about doctors on professional sport teams. A British inventor seems to have developed a fabric that loses its color and turns white above the standard temperature threshold.

From the Daily Mail:

Mr Ebejer, who had his idea while watching a documentary about babies, began the search for an ink pigment with heat-sensitive molecules.
He spent six years and £700,000 working with scientists to develop-the pigments to embed into cotton babygrows.
The blue Babyglow suit for boys turns white when the child's temperature rises too much

The blue Babyglow suit for boys turns white when the child's temperature rises too much. The Babyglows come in pink, blue and pastel green, all of which turn white as soon as the baby's temperature rises above 37c. They will be available from October for £20 a pack.

The worldwide patent has been bought by manufacturers Quality Workwear 4 U, in Milton Keynes.

Helmets Monitor Player Temperatures to Watch for Heat Stroke

Football players are prone to heat strokes due to the gear and helmets they wear, compounded by working out in off-season training facilities in places like Florida and Arizona. While training in 2001, Minnesota Vikings lineman Korey Stringer died due to heat stroke. To allow teams to monitor the players' individual temperatures, Hothead Technologies out of Atlanta, Georgia has developed sensors that can be built into helmets to provide live wireless updates.

From Popular Science:

The Heat Observation Technology (HOT) system uses an electric thermometer called a thermistor, a spoon-size device made of metals whose electrical resistance vary with temperature. Inserted under the padding of a standard helmet, the thermistor measures the temperature in the player's temporal artery and uses a built-in radio to transmit temperatures between 99.9° and 110°F — heat illness typically sets in around 104° — every 10 seconds to a PDA monitored by a coach or trainer on the sidelines.

NASA Creates New Sports Drink

As part of NASA's program to develop tools for astronaut training and living in space, researchers at NASA's Ames Research Center have developed a new hydration beverage that will rival Gatorade, itself originally created for the Florida Gators football team. The recipe has been licensed to a private firm, Wellness Brands, that will sell it under the name The Right Stuff.

From a NASA statement:

To help keep astronauts at peak performance during missions, NASA researched, qualified and patented a highly effective electrolyte concentrate formula that maintains and restores optimal body hydration levels quickly and conveniently. Developed as a remedy for dehydration, it helps prevent the loss of body fluids during heavy exercise, heat exposure and illness. It also can be used to treat and prevent dehydration caused by altitude sickness and jetlag.
NASA's Ames Research Center, Moffett Field, Calif., licensed the patented rehydration formula to Wellness Brands Inc., Boulder, Colo. Wellness Brands plans to launch its first electrolyte concentrate brand, 'The Right Stuff' in June 2009.

The novel electrolyte formula contains a specific ratio of key ingredients, sodium chloride and sodium citrate, for rapid restoration of hydration. These electrolytes, dissolved in water, optimize the levels of sodium ions in the body. The beverage is an isotonic formulation that restores both intra- and extracellular body fluid volumes in dehydrated astronauts, athletes and others.

Lactate Monitoring May Become As Common As Heartbeat in Sports

Measuring lactate levels in the blood is a common activity among athletes that closely monitor their condition. The process usually requires visiting a clinic, but now German researchers claim to have developed a scaled down version of the monitoring device that may soon find itself in over the counter lactate testers.

Fraunhofer-Gesellschaft reports:

“We have found a way of miniaturizing the measurement system so that it can be accommodated in an ear clip. The results could be radioed by the ear clip to a training wristwatch or a cellphone,” says Thomas van den Boom, group manager at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg. An electrochemical method is used to measure the lactate value. In a chemical reaction, an enzyme triggers a redox flow from the lactate which can be measured using electrodes. The measurement system, which could be installed for example in an ear clip, consists of two microchips: the innovative nanopotentiostat fits on a chip measuring just two by three millimeters and costs less than one euro. “The second chip incorporates microelectrodes which we have developed for this purpose and which we can couple with the nanopotentiostat,” explains van den Boom. One of the microelectrodes is coated with a thin layer of gel containing the enzyme. There are altogether three microelectrodes on the chip, which are activated by the nanopotentiostat. Two serve the purpose of electrochemical measurement while the third keeps the electrochemical potential constant end thus ensures a stable voltage.
The engineers can coat the electrode with different enzymes so that, apart from lactate measurement, various other analyses can be performed in the blood or other electrolytes. The advantage is that the electrodes are very small and cheap – and the analyses can be carried out in a mobile environment. A first demonstrator of the nanopotentiostat for lactate measurement (without earclip) has already been produced.

Gruve Helps Keep Weight Loss Exercise on Track

Using technology licensed from the Mayo Clinic, a company called Muve from Minneapolis, Minnesota has created a simple device that can help optimize exercise habits. Essentially a 3-D accelerometer, the Gruve from Muve is designed to measure person's movement and roughly convert that into calories expended. By setting weight loss goals, the unit can help the user optimize and when and how much movement needs to be done.

From the Associated Press:

As a lifelong runner and cross-country skier, Wood [Andy Wood, chief "muvologist" at Muve] was surprised by what his Gruve showed him. Days of sitting in the office broken up by a long distance run at lunchtime did not bring him to his green goal.
However, steady movement and small walks throughout the day, minus the noon-time run, did make his Gruve green.

After sitting for a long time, the body changes and begins creating fat instead of energy. Wood calls this the E.C.P or energy conservation point. His is 74 minutes and after 69 minutes of sitting, the Gruve vibrates like a cell phone to remind him to move.

Those little bursts of energy keep his body from shifting into neutral and creating excess weight.

High Speed RFID to Help Set New Records

RFID (radio frequency identification) technology is both controversial and amazing in its possibilities. In the field of sports, researchers are extending the precision of RFID to allow for accurate monitoring of performance. A new system attached to skis can provide feedback to a coach that is much more nuanced than an old fashioned video. The system has also the potential to improve safety for those who risk their lives on the giant slopes.

From Fraunhofer-Gesellschaft:

In the future, transponders – radio transmitters and receivers – will support coaches in their work. They can be attached to an athlete’s skis and transmit radio waves in every direction through small antennas one thousand times per second. The antennas are located to the front and the back of the skis. Receiving stations placed alongside a slope in regular intervals pick up the signals and analyze the time a signal needs to travel from the antenna to a station, thus accurately determining an antenna’s position within three centimeters. The underlying technology is radio frequency identification or RFID. A computer calculates the position of the skis every millisecond and displays their exact path on a monitor. “A coach recognizes whether both skis were parallel,” explains Richter, “whether the skier has drifted from her path in a curve and whether she is able to carve properly.” Carving involves taking the turns entirely on the edge of one’s skis.
The Austrian firm Abatec developed the system. Together with colleagues from the university in Magdeburg, the researchers at the Fraunhofer IFF are testing its systematic implementation in sports: What adhesive bonds the antennas to the skis so they do not loosen during a downhill run but can be detached when no longer needed? How can the radio signals be evaluated so a coach is able to draw conclusions about technique? Another challenge: Many skis contain metal layers of varying thicknesses, which shift a transmitter’s frequency. Depending on the skis’ design, the antennas transmit on another frequency and the base station no longer detects the signal. The solution: An additional metal plate under the antennas alters the signal so intensely and predictably that the slight differences between different skis are of no consequence: The antennas always transmit with the same controlled frequency. The technology performed well in initial tests in Bottrop ski hall and the system is now ready for use.
