Arm band informs you about body temperature rise

A team of scientists from the University of Tokyo has come up with a solar
powered arm band which plays an alarm if the user’s body temperature
gets high. This gadget will, reportedly, find its way to those who are
in charge of managing/monitoring more than one patient.

The gadget is comprised of a flexible silicon solar panel, a
piezoelectric speaker, power supply circuit and a temperature sensor.
All of these have been created by making use of organic components that
have been ink jet-printed onto a film of polymer. The band can be worn
directly against skin or on clothes.

Once the temperature sensor finds out that the user’s body
temperature has surpassed a preset range, the speaker plays an alarm.
This would be the first time, most likely, that the use of an organic
circuit has been employed for the purpose of creating sound.
 

This would
also be the first example of an organic power supply unit. Operational
indoor illumination of solar panels is increased by 7.3 times with the
help of this circuit.

The arm band is free from the need of any external power supply and
due its flexibility, it doesn’t cause any sort of discomfort to the
user. In order to maintain hygiene, it can be disposed off after each
use and its economic price helps in doing so.

Professor Takao Somey, co-leader of the research along with Professor
Takayasu Sakurai, said, “Our fever alarm armband demonstrates that it
is possible to produce flexible, disposable devices that can greatly
enhance the amount of information available to caregivers 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 this research will be presented at the 2015 IEEE
International Solid State Circuits Conference that will be held in San
Francisco.
