- Abstract:
- Piezoelectric materials enable the conversion of ambient vibration into electrical energy. The development of piezoelectric energy harvesting systems needs accurate models for systemperformance evaluation. Mechanical researchers build distributed models for energy scavengers, simplifying the energy harvesting circuit and using analytical derivation, while electrical researchers focus on the modeling of the energy harvesting circuit and simplifying the structural conditions of the scavenging devices. The challenges for accurate modeling of such electro-mechanical systems remain, when complicated mechanical conditions and practical energy harvesting circuits are considered in system design. This article addresses the abovementioned problem, employing an equivalent circuit, which bridges the structural modeling and electrical functionality, allowing simulations of complex circuitry. The equivalent circuit has been simulated using SPICE software. Measurements are performed for verification of the proposed model.
