—Towards Healthcare-Applicable Heartbeat and Pulse Sensors—

National Institute for Materials Science (NIMS)

National Institute of Advanced Industrial Science and Technology (AIST)

NIMS and AIST developed a liquid electret material capable of semi-permanently retaining static electricity. They subsequently combined this material with soft electrodes to create the first bendable, stretchable vibration-powered device in the world. Because this device is highly deformable and capable of converting very subtle vibrations into electrical signals, it may be applicable to the development of healthcare-devices, such as self-powered heartbeat and pulse sensors.
