Convert chemical energy to mechanical energy for use in robotics, wearable tactile interfaces, and active orthoses or prostheses.
Fluidic actuators require a pressure source, which limits their mobility and mainstream usage.
This invention uses a chemical approach to achieve portable and silent pressure generation. It specifically focuses on on-demand pressure generation by mechanical self-regulation of decomposition of hydrogen peroxide (H2O2) into oxygen (O2). Another key feature is its rotation-invariant usage, which allows the battery to operate in any orientation.
