A team of scientists from the University of Tokyo invented an armband made of organic materials and powered by solar energy. It can be worn on the patient's arm to monitor body temperature. If the patient has a fever, an alert will be issued to alert medical staff. The device contains a flexible amorphous silicon solar panel, piezoelectric speaker, body temperature sensor and power supply circuit made of organic materials. Components made of organic materials can ensure direct contact with the skin.
When the temperature of the patient wearing the armband rises within the set range, the speaker will warn. This is the first time that organic circuits have been used to power sound equipment, and it is the first time that organic power circuits have been used. This organic power circuit can also increase the indoor lighting sensing range of solar panels by 7.3 times. This arm ring device is inexpensive and requires no external power supply, and the human body can comfortably wear it.
This device proves that the circuits and components of organic materials can produce sensing devices that are very suitable for medical needs. It is expected to further develop the monitoring of heart rate and blood pressure in patients.
