An efficient piezoelectric energy-harvesting interface circuit using a bias-flip rectifier and shared inductor

Low frequency piezoelectric energy harvesting at multi vibration mode shapes

“…However, converting this mechanical energy into electrical output requires an electrical interface to transmit the output energy to the electrical load. In addition to the classic interface, various electrical interfaces have been developed to improve the output power of the piezoelectric energy harvesters such as: voltage doubler, synchronous charge extraction, parallel-synchronized switch harvesting on inductor (SSHI) and series-SSHI interfaces [32][33][34][35]. To investigate the potential improvements, parallel-SSHI M a n u s c r i p t 15 interface is simulated to estimate the maximum extractable power.…”

Explorations of displacement and velocity nonlinearities and their effects to power of a magnetically-excited piezoelectric pendulum

“…Among them, the most reputable field is energy harvesting due to their high power densities comparable to other regenerative energy technologies, such as lithium-ion batteries and electromagnetic power supplies [1][2][3]. Another need for piezoelectric harvesters is that the batteries require regular replacement; therefore an effective power saving strategy can be adopted to increase the life span of battery by using the harvesters [3][4][5]. This situation becomes much important if the devices are in hard environmental conditions in nature.…”

A review of piezoelectric energy harvesting based on vibration

“…Other approach using a bias-flip rectifier with an inductor was presented in the range of µW, which is greater than 4X power extraction compared to conventional full bridge rectifier. 92 However, due to the fundamental limitation of diode type rectification, built-in voltage in diode, to minimize the voltage drop to diminish the rectified output voltage from rectifying circuit in diode is the critical issue. At room temperature, the built-in voltage of Si and Ge based P-N junction diodes are about 0.7 V and 0.4 V, 93 respectively.…”
