A team of researchers at the University of Tokyo led by Professor Takayasu Sakurai and Professor Takao Someya, developed a smart armband which raises an alarm whenever the users run a high body temperature. The alarm in the self-powered armband is triggered when the thermal sensors embedded detect a body temperature between 36.5 and 38.5C. It is equipped with a piezoelectric speaker and a temperature sensor. They also used a flexible amorphous silicon solar panel and a power supply circuit to power the sensors and alarm. The fever alarm armband is 30 cm long, with a width of 18 cm, and can be worn over either on top of clothing or on the skin. The fever alarm armband represents numerous first-evers in the medical technology sector. It was the first organic circuit able to produce a sound output, which made it possible to sound the alarm. It was also the first device which uses an organic power supply circuit, which increases the range of illumination by 7.3 times in indoor lighting. While the device simply records body temperature, it can be made to sense the wearer’s wetness, blood pressure, and heart rate.
