Stamp-size patch harvests energy from a beating heart

Date:19 May 2014 Tags:,

A beating heart can become a power plant, thanks to a stamp-size patch that turns muscle movements into electricity. The device, which incorporates a lead zirconate titanate nanoribbon with gold wiring, generates an electric current as it bends and stretches. Applying a new fabrication process, researchers at the USA’s University of Illinois were able to use these types of high-quality materials for the first time. When they sewed the patch to the hearts, lungs and diaphragms of living animals, it could harvest and store up to 8 volts of electricity, with currents up to five orders of magnitude greater than in previous tests. That’s enough to power a pacemaker or other biomedical implants, such as blood-sugar monitors and neural stimulators, which need a battery change every five to 10 years.

Up next, the researchers will test the patch in long-term animal studies. Within five years battery-replacement surgeries could be obsolete.

Watch as the device is affixed to a bovine heart… (The anchoring scheme used sutures at three points to maintain focal contact, though without rigid attachment so as to minimise any alteration or constraint on cardiac motion.)

    So cruel using animals, abuse in capital letters, where’s peta, spca etc, can’t believe this kind of cruelty is being used in this age and day, what a disgrace!!!!!!!
