Dynamic Modeling Of Contact-Mode Triboelectric Generators By Lagrange’S Equations, Sean M. Gauntt, James Gibert

The Summer Undergraduate Research Fellowship (SURF) Symposium

Electret based energy scavenging devices utilize electrostatic induction to convert mechanical energy into electrical energy. Uses for these devices include harvesting ambient energy in the environment and acting as sensors for a range of applications. These types of devices have been used in MEMS applications for over a decade. However, recently there is an interest in Triboelectric generators/harvesters, i.e., electret based harvesters that relies on triboelectrification as well as electrostatic induction. The literature is filled with a variety of designs for the latter devices, constructed from materials ranging from paper and thin films; rendering the generators lightweight, flexible and inexpensive. …
