Electricity Generation From Human Breathing – University of Wisconsin

Developers have always been in search of alternative ways for the generation of electricity. Some of them have been the use of piezoelectric crystals that generate electricity from body movements, biological fuel cells which have the ability to produce electricity from blood sugar level of a person, and wireless transmission of power from outside the body. A new method has now been developed to produce electricity from a person’s breathing rate.

This device is manufactured by the University of Wisconsin, and it relies on piezoelectric effect, but contrary to relying on body movements to produce mechanical stress, this device makes use of speed of air flow that is a reason of a person’s respiration rate to cause vibration of the plastic micro belt engineering inside the device. This belt is made up to polyvinylidene fluoride (PVDF).
