Rochelle Salts
I've been looking into different ways to improve my headphone implants for a while now and I've stumbled on Rochelle Salts, which might have some great uses to our community. First off they are piezoelectric, so they can supply voltage when bent. Quite a bit of voltage actually. It is by no means a battery replacement but it might be ideal for some quick haptic actuator action like a small vibration motor or something.
If an implant is compromised and the rochelle salts get wet they just stop working. This lets you know the implant needs to be removed. Rochelle Salts are edible, so they are not likely to slay you if exposed to tissues.
Another thread discussed piezos being used as a charging method for implants. This material, stretched over discs that sandwich a magnet might be a good alternative to inductive charging because it would let you leach from ac currents without using a coil. What do you guys think?
