Scientists develop substitute for lead used in electronics

Lead is a toxic substance, and it’s in your mobile phone. It’s also probably in your TV, your computer, and just about any other electronic appliance where mechanical movement is transformed into an electrical signal. All those devices utilize PZT, a substance which contains lead, and that generates an electrical charge when subjected to pressure. While lead has been phased out of most consumer goods, a suitable alternative has never been found for use in electronics... until now, perhaps. Researchers at the Norwegian University of Science and Technology (NTNU) have developed an innocuous material with PZT-like qualities, and it’s made in a fashion somewhat like cookies.
