Pyroelectric energy conversion with large energy and power density in relaxor ferroelectric thin films | Nature Materials
low grade heat makes thermoelectric power generation a pain, but using a nanofilm and pyroelectric effects might work. ZT for 10 degrees is 1.16

Perpetual motion: A piezoelectric pacemaker that is powered by your heartbeat | ExtremeTech
Wow, that's actually pretty smart, if the local energy generation and storage for the periodic stimulus firing is sufficient and it isn't a large device to stuff into someones chest. Also much simpler and potentially more failsafe than say a blood sugar powered fuel cell.
