Abstract
A piezoresistive transducer is disclosed having a framework including a support element attached to a bending element that undergoes a deformation relative to the support element when a force acts on the bending element including a neutral fiber whose length does not change during the deformation. At least one piezoresistive expansion body is attached to the support element that exhibits a piezoresistive material and converts the deformation of the bending element into an electrically detectable change in resistance.
