The magnitudes of the voltage generated and the energy density harvested are shown as a function of the pads thicknesses, the speed and the temperature traversed by the pyroelectric material PZT.doi:10.1007/s40684-020-00195-6Yassine Tabbai
same as a regular brake pad making loud screeching caused by a short tab that only gets to contact the rotors when the pad thickness is reduced to very little. The red light is not based on any estimate, physically the pad that the sensor on has reduced its thickness to very little ...
