Nanogenerators Can Create Electricity From Blood Flow
A new invention can overcome the problem of periodically replacing implantable medical devices.
Dr. Yong Shi of the Stevens Institute of Technology has created extremely tiny generators that can be implanted in the human body to harness the mechanical energy of flowing blood to create electricity.
The minute generators were made from placing several piezoelectric nanofibers, that are microscopic wires capable of using mechanical energy from nearby and converting it into electrical energy, on a piece of silicon. Dr. Shi's team was able to generate a small amount of power from the generators in their experiments and hope to use them in biosensors and in powering implantable medical devices in the future.
