The human body must stay within a certain temperature range for comfort and safety. However, challenges thermoregulatory clothing exist harsh application scenarios, such as full day/night cycles, frigid polar regions, space travel. We developed flexible sustainable personal system by integrating organic photovoltaic (OPV) module to directly acquire energy from sunlight bidirectional electrocaloric (EC) devices. OPV-EC (OETC) can extend the thermal zone 22°-28°C 12.5°-37.6°C with fast thermoregulation rate. low consumption high efficiency of EC device allows 24 hours controllable dual-mode 12 input. This self-powered wearable platform has simple structure, compact design, efficiency, strong self-adaptability sole source.

Materials Today Energy, Год журнала: 2023, Номер 32, С. 101257 - 101257

Опубликована: Янв. 21, 2023

Buildings consume almost one-third of the total global energy and emit nearly 15% direct CO2 generated on planet. However, intelligent buildings taking advantage modern efficient technologies have attracted large interest in recent years. In this regard, application various harvesters to convert different forms present inside around into electrical has been widely investigated. These include photovoltaic, piezoelectric, pyroelectric, electromagnetic, thermoelectric devices. Among them, generators (TEGs), capable producing electricity directly from a temperature gradient, demonstrated great potential. This review paper categorizes explains plausible applications materials devices buildings. particular, state-of-the-art cement- concrete-based composites potential TEGs windows, walls, pipes, chimneys are discussed. Moreover, current challenges that face practical approaches tackle them examined.
