Creation of a power-generating, Gel Electret-based device

Research Press Release | July 05, 2024

A power-generating, Gel Electret-based device has been created, which may be used to develop soft, lightweight wearable motion sensors for healthcare purposes.

A team of researchers from NIMS, Hokkaido University and Meiji Pharmaceutical University has developed a gel electret capable of stably retaining a large electrostatic charge. The team then combined this gel with highly flexible electrodes to create a sensor capable of perceiving low-frequency vibrations (e.g., vibrations generated by human motion) and converting them into output voltage signals. This device may potentially be used as a wearable healthcare sensor.

The complete press release is available on the NIMS website, and can also be downloaded as a PDF.
