The ceramic produced in Prof. Igor Lubomirsky's lab at the Weizmann Institute of Science seemed too good to be true. It belongs to a class of materials that are the backbone of many essential technologies but that unfortunately also create an environmental problem because they usually contain lead, which is highly toxic. The surprising thing about the Weizmann ceramic was that it could perform just as well as other materials in this category while being entirely nontoxic. The research is published in the journal Nature Communications.

Nano-thin piezoelectrics advance self-powered electronics

A new type of ultra-efficient, nano-thin material could advance self-powered electronics, wearable technologies and even deliver pacemakers powered by heart beats.

so if there's any chance any of you guys know how to use piezos and feel like giving me some advice it'd be very much appreciated I'm thinking of buying some 15-mm piezo discs (like the kind used in cigar box guitar pickups and stuff) and attaching them to my laptop keyboard to harness the power from my typing. ideally I'd use them to power a small motor but I'm not sure it would ever produce enough power to start it, let alone keep it running with any noticeable strength, but I could be wrong. I've never really worked with piezos before except to push on them and see the numbers go up and down on a multimeter, and I'm having a hard time finding resources about them online that aren't graduate-level research papers way above what I'm trying to do
