Researchers have recently developed a printable armband that monitors vital signs including temperature, heart rate and sounds an alarm in case of high body temperature.
The new device 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 combines a flexible amorphous silicon solar panel, piezoelectric speaker, temperature sensor, and power supply circuit created with organic components in a single flexible, wearable package.
The fever alarm armband incorporates several first-ever achievements. It was the first organic circuit able to produce a sound output, and the first to incorporate an organic power supply circuit.
