In a bid to turn the fantasy of battery-less gadgets into reality, a team from Carnegie Mellon University has introduced Power-Over-Skin. This cutting-edge innovation enables electric currents to course through human skin to energize objects like pacemakers, glucose monitoring devices, and trending wearable gadgets such as smart eyewear and fitness trackers.
While the technology is still budding, its potential is representing a new energy paradigm. Presently, its applications have been demonstrated for low-power digital devices, as exemplified by an LED earring.
Drawing a parallel to a simple radio system, researcher Andy Kong noted, “Just as a radio uses air as the conduit between the transmitter station and your car radio, we’re exploiting body tissue as the transmitting medium in this scenario.”
