Heat is an abundant but often wasted source of energy. Thus, harvesting just a portion of this
tremendous amount of energy holds significant promise for a more sustainable society …

As an extended member of the thermoelectric family, ionic thermoelectrics (i‐TEs) exhibit
exceptional Seebeck coefficients and applicable power factors, and as a result have …

Benefiting from the inherent properties of ultralight weight, ultrahigh porosity, ultrahigh
specific surface area, adjustable thermal/electrical conductivities, and mechanical flexibility …

Carbon‐based nanomaterials, including graphene, fullerenes, and carbon nanotubes, are
attracting significant attention as promising materials for next‐generation energy storage …

With the ever-growing development of multifunctional and miniature electronics, the
exploring of high-power microwatt-milliwatt self-charging technology is highly essential …

Low-grade heat (below 373 kelvin) is abundant and ubiquitous but is mostly wasted
because present recovery technologies are not cost-effective. The liquid-state thermocell …

Harvesting heat from the environment into electricity has the potential to power Internet-of-
things (IoT) sensors, freeing them from cables or batteries and thus making them especially …

Restricted ambient temperature and slow heat replenishment in the phase transition of water
molecules severely limit the performance of the evaporation-induced hydrovoltaic …

As an extraordinarily lightweight and porous functional nanomaterial family, aerogels have
attracted considerable interest in academia and industry in recent decades. Despite the …

Thermocells hold great potential for continually harvesting waste heat to power ubiquitous
electronics, but their integration is hampered by leakage risk and poor mechanical …
