In: 2023 IEEE 22nd International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS), 11-14 December 2023, Abu Dhabi, United Arab Emirates979-8-3503-4422-6https://doi.org/10.1109/PowerMEMS59329.2023.10417175https://dspace.lib.cranfield.ac.uk/handle/1826/21193This paper evaluates a novel design of a bridge shear-force structure used to transfer large compressive loads into shear loads on the surface of a piezo disc. The wave/crinkle design can increase the overall number of bridges in a concentric orientation to the circumference with the aim of producing multiple shear force pinch points, changing the shear mode extension path along the piezo discs' axial plane, allowing for tunability, and increasing electrical energy output of a Piezoelectric Energy Harvester (PEH).en-UKAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/PiezoEnergy HarvestingShearCompressionSpring WasherCrinkle WasherWave springHigh force compression mode to shear mode piezoelectric energy harvestingConference paper979-8-3503-4421-9
