Thermal Energy Harvesting In article number 2110288, João Ventura and co‐workers demonstrate a hybrid device that couples triboelectric and thermomagnetic effects to generate useful electrical energy in the presence of small temperature gradients near room temperature (from 15 to 37 °C in the cold side and from 60 to 90 °C in the hot side). The versatile prototype generates 35 times more power than a conventional thermomagnetic generator driven by magnetic induction, expanding the applicability of triboelectricity into the realm of room temperature thermal harvesting.
