Research Project Title:

Design of a Piezoelectric (PZ) Energy Harvesting Device (EHD) for Wide-Bandwidth Harvesting of Vibration Energy

abstract:Harvesting energy from the environment is a key technology that is being developed to power sensor nodes in embedded systems. This project focuses on harvesting vibrational energy using a PZ EHD. When vibration energy excites such a device at its mechanical resonance frequency, adequate output power is achieved. But for excitations away from resonance, the power decreases rapidly. Using an electrical loading technique, referred to as "Bias Flip", one can shift the resonant frequency of the EHD. This has proven to be successful for small frequency mismatches, but the goal is to achieve high output power over an even wider bandwidth.
About:

I'm participating in this SuperUROP because I would like to apply my knowledge of circuits and electronics to a project that has immediate real world applications. This project would allow me to simulate and test a device with my input. I would like to further deepen my knowledge in circuits and how one can effectively use them to solve problems.
