Scientists develop new material that repairs itself without external intervention SECTIONS Last Updated: Jul 29, 2021, 10:10 AM IST Share iStock Cluster of raw piezoelectric crystals 3D (Representative Image) NEW DELHI: Scientists have developed piezoelectric molecular crystals that repair their own mechanical damage without the need for any external intervention, the Department of Science and Technology (DST) said on Saturday. Piezoelectric crystals are a class of materials that generate electricity when it undergoes a mechanical impact. Devices that are used daily often break down due to mechanical damage, forcing users either to repair or replace them. This decreases the life of the equipment and increases maintenance costs. In many cases, like in a spacecraft, human intervention for restoration is not possible.
