Indian Scientists have developed piezoelectric molecular crystals that repair their own mechanical damage without the need for any external intervention.
Daily Current Affairs Quiz 2021
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.
The piezoelectric molecules developed by the scientists called bipyrazole organic crystals recombine following mechanical fracture without any external intervention, autonomously self-healing in milliseconds with crystallographic precision.
In these molecular solids, due to the unique property of generating electrical charges on mechanical impact, the broken pieces acquire electrical charges at the crack junction, leading to attraction by damaged parts and precise autonomous repair.
