Solar powered skin device to monitor heart!

Most of the medical monitoring devices need external power supply to operate efficiently. With modernisation next-generation biomedical devices will need to be self-powered and conformable to human skin or other tissue. Such devices would enable the accurate and continuous detection of physiological signals without the need for an external power supply or bulky connecting wires.

Now scientists have developed sunlight powered ultra flexible organic sensor to monitor heartbeat in bright light condition. Self-powered devices that can be fit directly on human skin or tissue have great potential for medical applications. They could be used as physiological sensors for the real-time monitoring of heart or brain function in the human body. 

According to Kenjiro Fukuda of the RIKEN Center for Emergent Matter Science, “This is a nice step forward in the quest to make self-powered medical monitoring devices that can be placed on human tissue. There are some important remaining tasks such as the development of flexible power storage devices3D and we will continue to collaborate with other groups to produce practical devices.” This innovation offers a general platform for next-generation self-powered electronics. The research was carried out by RIKEN in collaboration with researchers from the University of Tokyo.

Cardiac monitoring is used to either identify or rule out a heart rhythm disorder and to determine the right course of treatment. Cardiologist may recommend continuous heart monitoring to assist in diagnosis of health conditions, including:

  • Unexplained Fainting
  • Unexplained Stroke
  • Heart Palpitations
  • Atrial Fibrillation

Common types of cardiac monitoring systems offered by leading medical device manufacturer Medtronic are:

  • HOLTER MONITOR: It is a portable external monitor consisting of wires with patches which are attached to the skin. It continuously measures and records the heart’s activity for 1-2 days.
  • EVENT RECORDER: It can be worn on the body up to a month and needs to be activated by push button to record activity of heart.
  • MOBILE CARDIAC TELEMETRY (MCT): It detects, records and transmits abnormal heart rhythms up to a month.
  • INSERTABLE CARDIAC MONITOR (ICM): It is placed under skin and automatically detects and records abnormal heart rhythms for up to 5 years.
