A simulation design based on piezoelectric-photoelectric composite energy harvesters is proposed to solve the limitation that different energy harvesters can only work under certain conditions. The design of composite energy harvesting can capture sunlight and produce electrical energy and can also harvest vibrational energy in the environment to generate electricity from it. Cantilever beams with 6 different structures are simulated. The resonance frequency of the T-shaped cantilever beam is only 40 Hz, which can be used to collect vibration energy in the environment. The effect of different thicknesses of perovskite solar cells on the output performance was simulated. When the perovskite layer was 500 nm thick, the open circuit voltage could reach 1.08 V. The piezoelectric module and the photoelectric module are integrated into the energy collection circuit, which can collect vibration energy and light energy at the same time. The maximum output power may be obtained as 290 μW when the load resistance is 35 KΩ, and the output voltage at this time is 3.18 V. The structure broadens the application environment of the energy harvester and has the function of improving the output.

This paper aims to examine the influence of gravity on a thermoelastic microelongated layer when a piezoelectric layer is above it, utilizing the theory of Lord-Shulman (L-S) and also the model of dual-phase-lag (DPL). A partial differential equation was transformed into an ordinary differential equation using the normal mode analysis. Aluminum epoxy numerical computations are carried out, and the results are presented in graphical format. The L-S theory and the model of DPL are compared in the presence and absence of gravity and it is found that gravity has quite a massive influence on all the physical quantities.

“…The transducer mainly consists of two piezoelectric cantilever beams. Based on previous studies for reference, [48,49] the main variables studied in this article are the rotation angle of the transducer and the distance between the two magnets. The special shape of the sickle-shaped cantilever beam type allows this harvester to produce peak voltage at several optimal wind speeds and has a high voltage output at wind speeds from 5.37 to 18.23 m s À1 .…”

Achieving broadband energy harvesting at low frequencies is a difficult area of research today. To solve the aforementioned problems, herein, a nonlinear sickle‐shaped cantilever beam piezoelectric energy harvester (S‐PEH) for wind energy harvesting is proposed. It has a high‐voltage output in the wind speed range of 5.37–18.23 m s−1. The S‐PEH is consists of a collector and a transducer. The collector converts wind energy into rotating mechanical energy and excites the transducer by means of magnetic coupling, thus realizing the conversion of mechanical energy to electrical energy. The special structure of the transducer's sickle‐shaped cantilever beam type can effectively harvest wind energy in low‐frequency environment and broaden the range of harvesting wind speed in high voltage. The structure and principle of S‐PEH are analyzed by theory and simulation and are experimentally verified. The results show that when the magnet on the rotor is 15 mm away from the magnet of the piezoelectric sheet, the transducer angle is 90°, the load resistance is 100 kΩ, the voltage of the blower is kept at 120 V, and the system has a maximum power of 563 μW. Moreover, it can successfully make low‐power electronics work.
