A nonlinear interface circuit, known as synchronized switch harvesting on inductor (SSHI), for in-plane rotational electret kinetic energy harvesters (EHs) was developed. An explicit generator model is derived to verify the applicability of SSHI, whi

In this paper, we investigate the effect of natural frequency of rotational energy harvester (EH) on power generation characteristics during human walking. Based on electromechanical analysis using the arm swing model, it is found that the output pow

A stochastic model of arm swing is proposed for standard test of rotational energy harvester (EH). Based on the mean values and standard deviation of the frequency and amplitude of arm swing from walking experiment, the output power of rotational ele

Large-scale vortical structures and associated mixing in methane/air swirling coaxial jets are actively controlled by manipulating the outer shear layer of the outer swirling coaxial jet with miniature flap actuators. In order to investigate the cont

A dynamic model of arm-equipped rotational energy harvester (EH) during human walking is proposed. The model describes realistic arm swing based on a two link with shoulder and elbow joints rotation, and includes the electro-mechanical coupling with

A MEMS electret vibration energy harvester with an embedded bistable electrostatic spring for broadband response is proposed. By using a vertical electret, the bistable potential can be realized without any complex structure or additional mechanism.
