Nanogenerators Use Energy From Their Environment To Power Devices
Tiny generators capture waste energy to power electronic gadgets.
A Georgia Tech professor and his team have been able to develop nanogenerators that harvest mechanical energy from the environment to power small electronic devices. Zhong Lin Wang’s devices are made from arrays of tiny nanoscale zinc oxide wires which use electric charge created by flexing or compressing the wires to produce a small amount of current. Wang says that this process can be scaled to a higher level to have real world applications in the fields of health care, electronics and environmental monitoring.
