“…These characteristics result in a lower energy capture density. To expand the bandwidth and enhance the power generation efficiency of the structure, various structural configurations have been proposed and analyzed [ 6 , 7 ]. Examples of such structural configurations include cross-sectional beam harvesters, tri-directional broadband harvesters, horizontally asymmetric U-shaped harvesters, fan-shaped vibration energy harvesters for leadless pacemakers, multi-directional harvesters for human motion, cross-shaped harvesters, and L-shaped beam piezoelectric energy harvesters [ 8 , 9 ].…”

In this article, an L-shaped three-dimensional (3D) braided piezoelectric composite energy harvester (BPCEH) is established, which consists of an elastic layer composed of a 3D braided composite, flanked by upper and lower layers of piezoelectric material and two tuning mass blocks. Glass fiber and epoxy resin are used to produce a 3D braided composite. This L-shaped 3D BPCEH is mechanically designable and can be adapted to different work requirements by varying the braided angle of the 3D braided composite layer. The material parameters of 3D braided composites are predicted for different braided angles by means of a representative volume element (RVE). Electro-mechanical coupled vibration equations for the L-shaped 3D BPCEH are established. The impact of braided angles on voltage and power output is discussed in this article. Simulations using finite element method are conducted to analyze the voltage and power output responses at various braided angles. In addition, the effects of the mass of mass block B and the length of the beam on the output performance of the L-shaped 3D BPCEH are analyzed.

“…The matrix of the 3-D BCM is made of TDE-85 epoxy resin, the fiber is made of glass fiber-S, while all fibers have a circular cross-section, it should be noted that some fibers exhibit an elliptical cross-section due to their non-perpendicular orientation with respect to the direction of the cross-section, as shown in Figure 2. The material parameters of TDE-85 and glass fiber-S are shown in Table 2 [40], and the material parameters of PZT-5H are shown in Table 3 [41]. The braided angle is the angle between the direction of fibers and the direction of braiding, and the mechanical performance of the 3-D BCM can be changed by changing the braided angles.…”

In this article, the piezoelectric patches are embedded into three‐dimensional (3‐D) braided composite material (BCM), and a 3‐D embedded braided composite piezoelectric vibration energy harvester (BCPEH) is designed. The 3‐D embedded BCPEH can be applied in more complex working environments to protecting the piezoelectric patches, and has a longer lifespan. The material parameters of the 3‐D BCM are obtained by analyzing the representative volume units (RVU). Using Hamilton's variational principle, the vibration control equation, and the output voltage and power expression are derived. The influence of excitation frequency, load resistance, and external excitation on the output voltage and power are simulated under different braided angles and embedded depths.
