Abstract

An example circuit for reading data from a triboelectric sensor includes a triboelectric sensor and a sensing element electrically coupled to the triboelectric sensor and configured to output a signal in response to a change in voltage from the triboelectric sensor. The sensing element may include a first thin film transistor electrically coupled to the triboelectric sensor. The circuit may further include a load element electrically coupled to the sensing element and configured to supply a load to the sensing element. The triboelectric sensor, the sensing element, and the load element may be disposed on a flexible substrate.
