Interdigitated electrodes are a type of electrode configuration used in various devices, particularly in piezoelectric energy harvesting systems. This design features two or more sets of fingers or comb-like structures that alternate between positive and negative connections, maximizing the surface area for interaction with piezoelectric materials and enhancing charge generation efficiency. By providing a greater electric field across the piezoelectric material, interdigitated electrodes play a critical role in determining coupling and efficiency in energy harvesting applications and are integral to the operation of MEMS-based devices.
