Solar-Powered Armband Monitors Fever

Feb-25-15 A solar-powered, disposable armband able continuously monitor a patient's temperature could take some of the burden off caregivers who are responsible for several patients.

A team from the University of Tokyo created the armband by jet-printing its organic components onto a thin, polymer film. The armband consists of a silicon solar panel, piezoelectric speaker and power supply circuit, and it can function both under and on top of clothing. The temperature threshold can be set by the caregiver, and the armband will emit an audible alarm if that limit is reached. The construction of the device is remarkable in itself, as it is the first example of an organic circuit being used to create both sound and a power supply.

The team believes the armband could be adapted to monitor other vitals and conditions, such as heart rate, pressure and moisture.
