Abstract

Researchers present the first triboelectric nanogenerator (TENG)-based self-powered implantable drug-delivery system (iDDS) for drug-delivery applications. The device comprises an electrochemical microfluidic pump which is powered by TENG. The working performance of the self-powered device is characterized. As a demonstration, trans-sclera drug delivery is performed in porcine eyes ex vivo. The iDDS derives its functional power from the energy harvested from human body’s motion through TENG for drug delivery.
