This paper reports on an electrostatic vibration energy harvester (e-VEH) system with variable area, variable permittivity, and variable radius. Nonlinear oscillator equations are established for each case, and solved analytically and numerically. The power produced by each configuration of the harvester is presented in terms of resistive load, frequency and external excitation.
