What is Effect of Slots in a Cantilever Beam for Improved Piezoelectric Vibration Energy Harvesting about?

In this paper, cantilever beams with different slot designs are studied for power scavenging through the piezoelectric patch. The slots of various dimensions are incorporated to study the strain distribution in the beams, as maximum strain distribution contributes to maximum power output through piezoelectric energy harvesting. Numerical finite element method (FEM) simulation is performed using COMSOL software to get the stress, strain, resonant frequency, and voltage generated through L-shaped lead zirconate titanate (PZT-5A) patch for different beams. Experimental work is performed by providing harmonic excitation to the slotted beam with an L-shaped PZT patch for verifying the resonant frequency and maximum voltage. The power output from various beams with multi-slots and beams with a single slot is compared with the power output from beams without slots used by researchers in the past. This research concludes that a cantilever beam with slots can harvest energy from vibration sources with low frequency. Moreover, the beam with a single slot provided larger power output than the beam with multiple slots. The power density output is found to be increased by around 70% by inducing
