The new "liquid electret" material has the mechanoelectrical and electroacoustic functions, as well as the flexibility and stretchability, that would be crucial in a reliable and long-lasting power source for such devices.
Key Points:
- The new "liquid electret" material has the mechanoelectrical and electroacoustic functions, as well as the flexibility and stretchability, that would be crucial in a reliable and long-lasting power source for such devices.
- Electrets are key components for powering mechanoelectrical devices as they behave like a battery or as an electrical counterpart of a permanent magnet.
- However, a liquid electret material would be a better solution -- it would be flexible and stretchable, and greatly enhance the usability of the devices they power.
- In addition, liquids offer fluidity with fast diffusion of molecules, easy processing, lack of defects and high deformability -- all requirements for flexible/stretchable device technologies.
