چکیده

In this paper we describe the system design of a piezoelectric MEMS energy harvesting module based on analytical modeling. The application example of a wireless sensor node for tire condition monitoring is considered. Key specifications which are taken into account are the power budget for the system operation, the system mass and the area consumption. System considerations comprise the generator design, material impact and the generator interface circuitry. A design procedure is presented, which allows identifying a geometry design space for the piezoelectric microgenerator consistent with required boundary conditions and specifications.
