Thermoelectric Power Generator: A Cool Chip


IME researchers have developed and demonstrated a Si nanowire based thermoelectric generator (TEG) for site-specific cooling applications. Conventional TEGs are based on bulk materials that are expensive, and are not amenable to scaling and integration with conventional electronics. Not only is the proposed TEG CMOS-compatible and scalable, it enables ready integration onto a chip level. The integrated chip size TEG could be used in miniature medical devices and high performance computing units for temperature control purpose.
