Design and experiments of a thermoelectric-powered wireless sensor network platform for smart building envelope

A new thermoelectric-powered wireless sensor network platform is presented for the low-cost environmental sensing in building envelopes through thermoelectric energy harvesting and ultra-low power management. It designed prototyped entirely inside a window frame without compromising architectural aesthetics. This self-powered achieved by maximizing harvested from optimizing unit’s consumption. harvests milli-watt level temperature gradient across generators with an optimized thermal connector. The voltage-boosted regulated two integrated circuits that are tailored ultra-low-power input. low system-on-chip used to supervise data communication. consumption adjusting system sleep time match energy. proposed thoroughly tested, where 1.5 mW of under 6 °C difference, 33.4% efficiency battery. In meantime, 0.42 consumed unit sampling period 2 h, which reaches equilibrium state. algorithm can project battery based on historical weather conditions, so as achieve condition given geographic location. smart envelope systems include unique innovations architecture, thermally internal structure,
