In this work we present a thermoelectric energy harvesting system consisting of a miniaturized and wearable flexible thermoelectric generator (TEG) and a dedicated ASIC, finalized to efficiently recover and manage energy from heat dispersed into the environment. The proposed TEG was realized on flexible Kapton substrate, which is particularly appreciated for its optimum properties of chemical and physical stability, permeability to atmospheric agents (humidity, oxygen) and thermal conductivity. Contrary to a conventional rigid substrate, like glass or silicon, a flexible one adds to the device lighter weight, increased robustness, freedom of shape, compactness, and low cost. Although the TEG was designed as "electronic garment" for wearable use in Ambient Assisted Living (AAL) applications, the device can be easily adapted to different contexts thanks to its flexibility and design that extend the application range to …
