Researchers have made a flexible armband at university of Tokyo known as "fever alarm armband."It is a self-powered device, can be wore on an arm which sounds an alarm in case of high body temperature.It is introduced on 22 to 26 February this year at the International Solid State Circuits Conference, San Francisco.This armband is 30 cm long and 18 cm wide.
The device contains a flexible amorphous silicon solar panel, temperature sensor, piezoelectric speaker, and power supply circuit produced with organic components in a single flexible, wearable package.It is a health indicator device which constantly monitor heart rate and body temperature.It has flexible and wireless sensors that don't need any external power supply and maintenance free as well.It also gives an opportunity to get print of incorporates organic components by an inkjet printer.It is the first organic circuit capable to make a sound output, and the first to integrate an organic power supply circuit.
The device has developed by research groups lead by Professor Takayasu Sakurai at the Institute of Industrial Science and Professor Takao Someya at the Graduate School of Engineering.Professor Someya said, "Our fever alarm armband proves that it is possible to
produce flexible, disposable devices that can greatly enhance the amount of information available to carers in healthcare settings." "We have established 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."
