Abstract: The self-powering problem of massive low-power wireless sensors in the internet of things (IOTs) is a hot topic in the
microelectronics field, and has not been well solved so far. The traditional magnetically coupled bistable piezoelectric vibration
energy harvester cannot meet the self-powering needs due to its narrow bandwidth and low efficiency. In order to improve the
comprehensive output performance of the bistable piezoelectric vibration energy harvester, this paper presents a programmable 3D
printed asymmetric bistable piezoelectric vibration energy harvester. An asymmetric potential energy well raceway designed by
programmable and 3D printing techniques replaces the traditional magnetic coupling structure to a generate nonlinear repulsion
force, which excites the piezoelectric vibration energy harvester to generate an inter-well motion with a large amplitude, thereby
improving the working bandwidth and generation efficiency of the piezoelectric vibration energy harvester. A nonlinear
electromechanical coupling dynamic equation for the presented bistable piezoelectric vibration energy harvester was established
using Hamilton energy method and Lagrange equation. The influences of different parameters of the programmable raceway on the
dynamic output performance of the piezoelectric vibration energy harvester were simulated and experimentally studied. The
research results indicate that the operating frequency bands of the three programmable raceway structure piezoelectric vibration
energy harvesters are 4.6, 2.6 and 1.7 Hz, respectively. The normalized power output densities reach 16.163, 15.6 and 14.151 mW∙

cm ∙g ∙Hz , respectively, which meet the self-powering supply requirements of low-power wireless sensors. The programmable
design method based on 3D printing proposed in this article has the advantage of being simple and flexible. Users can customize the
personalized bistable piezoelectric vibration energy harvester according to different external environments of sensors.
