How are peacemaker batteries replaced
How are peacemaker batteries replaced
Peacemakers need to be fitted with a new battery once every eight to twelve years, and so far this has involved an operation every time one had to be replaced. The hope is that this may be avoided in future, thanks to new developments. One Japanese invention is a device with a solar cell that is inserted under the skin. When an infrared laser beam is directed at it, the battery is recharged. In America, scientists are working on implants that are automatically provided with a lasting supply of energy from tiny, thermoelectric elements that drive their energy from the bodys own heat. Other researchers are working on a biofuel cell - a mini-battery that takes its energy from the blood. It imitates natural metabolic reactions involving blood sugar and oxygen, transforming chemical energy into electrical energy.
