Scientists at Indian Institute of Science (IISc), Bengaluru have developed a new type of energy harvester that uses piezoelectric and electrodynamic mechanisms in a single device.

Energy harvesters are devices which converts ambient sources of energy like solar, wind, thermal or mechanical, into usable electricity. Unlike energy producers which consume fuel to produce energy, energy harvesters can only convert one type of energy into another usable form, usually electricity and often run on renewable energy sources.
