Human heat flux is ~50-100 W/m², but TEGs are <8% efficient. Solution: Hybridize with piezoelectric pads (capture impact energy) under the same play surface.
These are solid-state devices that use the Seebeck effect. When one side of a semiconductor is hot (from a child's palm) and the other side is cold (ambient air), electrons flow, creating direct current (DC) electricity. digital playground body heat install
On a 30°C summer day, ΔT collapses. Solution: Passive evaporative cooling on the cold side (porous ceramic reservoirs) to maintain a 10°C sink. Human heat flux is ~50-100 W/m², but TEGs
