Energy harvesting optimization for built-in power replacement of electronic multisensory architecture

摘要

In this work, we present a novel multisensory electronic architecture that can work with very low voltage requirements thus enabling power management directly from harvesting-based low-voltage sources. The harvesting system here proposed relays on thermoelectric generator cells useful for furnishing additional power to an electronic system made of a home-made sensory glove, an inertial measuring unit, and an electromyography device, aimed at providing full measures of the arm-hand dexterities. The thermoelectric generator cells are optimized to work as an array configuration up to 10 cells series-connected and the energy conversion is managed with a commercial DC/DC with MPPT algorithm.
