  • Piezoresistive transducer
    Patent number: 9063167
    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.
    Type: Grant
    Filed: February 28, 2011
    Date of Patent: June 23, 2015
    Assignee: FRAUNHOFER-GESELLSCHAFT ZUR
