Researchers at University of Tokyo have come up with a solar powered arm band that sounds an audible alarm if the wearer’s body temperature rises above normal. The quality of healthcare will improve at hospitals with the creation of solar-powered arm band as it will help in monitoring multiple patients at a time in hospitals upon commercialization.
The device is made of organic components (flexible amorphous silicon solar panel, a piezoelectric speaker, a temperature sensor, and a power supply circuit) which are printed on a polymer film with the help of an ink jet printer.
It is a major breakthrough in the health care field for Japanese researchers because the organic components have been used for the very first time for power supply and to produce sound. The organic power supply circuit boosts the solar panel’s range of operational indoor illumination by 7.3 times. There is no need of any external power supply for the arm band.
Other advantages of the arm band include flexibility, comfort and cost effectiveness. It also helps in improving hygiene levels as it is cheap enough to be disposed after each use.
Commenting on the new technology, Prof. Takao Someya, who co-led the research along with Prof. Takayasu Sakurai remarked, “Our fever alarm armband demonstrates that it is possible to produce flexible, disposable devices that can greatly enhance the amount of information available to care givers in healthcare settings. We have demonstrated the technology with a temperature sensor and fever alarm, but the system could also be adapted to provide audible feedback on body temperature, or combined with other sensors to register wetness, pressure or heart rate.”
A paper on the research will be presented at the 2015 IEEE International Solid State Circuits Conference, in San Francisco.
