This paper presents an investigation into the influence of varying potential well depths on performance a dual−coupled beam energy harvester (DEH). Firstly, three were established with different polynomial coefficients nonlinear restoring force and analyzed in simulation. Numerical results revealed that whether initial depth is shallow or not, optimal power output can be attained when stiffness coupling spring half monostable−to−bistable stiffness, which was also validated by experiment. Specifically, at deeper 0.64 mJ, system demonstrated superior conversion capabilities. Compared to traditional BEH LEH, RMS voltage Beam 1 total DEH increased 103.06% 49.6%, respectively. The 16.4% 0.9 mJ. In addition, regardless depth, always achieve operating bandwidth near transition region.
