What’s common knowledge in your field, but shocks outsiders? Some computer Flash Memory relies on electrons 'magically' transporting from one side of an insulator to another via quantum tunnelling.

I just found one of my original photos of the fingertip. Even in 2017 it was possible to squeeze a MEMS pressure sensor, temperature sensor, microphone, opamp and ADC onto this tiny PCB. Around the outside is wound a nichrome heater. The 'skin' is moulded RTV silicone.

I love it when I can re-purpose an old PCB for a new project. This is a prototype water quality (TDS) sensor. The electronics were originally part of a biomimetic robotic fingertip sensor that I designed nearly a decade ago. It has a nice low-noise op-amp and I2C ADC on it which found use here.
