New Stretchable Battery for Stretchable Electronics
Posted in Batteries, Electronics, Implants & Prosthetics, Medical, News, MDB on Monday, 04 March 2013
Researchers at Northwestern University, Evanston, IL and the University of Illinois have demonstrated a stretchable lithium-ion battery can power their innovative stretchable electronics. The stretchable electronic devices now could be used anywhere, including inside the human body, they say, powering implantable electronics that could monitor anything from brain waves to heart activity. They say that they have demonstrated a battery that powers a commercial light-emitting diode even when stretched, folded, twisted, and mounted on a human elbow. The battery can work for eight to nine hours before needing recharging, which can be done wirelessly.

Self-Charging Power Cell for Small Devices
Posted in Bio-Medical, Electronics, Batteries, Electronic Components, Power Supplies, Medical, Briefs, MDB on Friday, 01 February 2013

A hybrid power cell uses a new technique for electrical charge conversion and storage.

Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.

The Future of Iron-Air Batteries
Posted in Batteries, Energy Storage, Solar Power, Energy Efficiency, News on Thursday, 02 August 2012
A University of Southern California research team has developed a cheap, rechargeable battery that could be used to store energy at solar power plants for a rainy day. The air-breathing battery uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air — a process similar to rusting.
