This innovative new technique allows resistors, capacitors, and integrated circuits to be removed intact, thereby eliminating downtime between recovery and reuse. Amazingly, the self-disassembling circuit board is made of unzippable polymeric […]

They found a serious glitch in current piezo devices that keeps them from giving their best at converting mechanical stress to electricity. Despite the fact that the powers outputted by piezoelectric devices are small (per […]
