Abstract. This paper investigates by numerical simulation the performance of an electrostatic vibration energy harvester when it is electrically configured in two different diode-capacitor multiplier topologies. The complete lumped-model of an overlap-varying generator along with power electronic interface circuit is constructed for analysis using a crcuit simulator. Parasitic capacitance of the transducers and nonideal diode traits such as leakage current and junction capacitance are incorporated. We find that both configurations are able to efficiently operate with a ratio of capacitance variation much lower than 2, which overcomes a challenging obstacle of MEMS-based devices. Other advantages and disadvantages of the two topologies are compared and discussed.

Abstract-This work presents a rigorous electrical analysis of charge-pump conditioning circuits for capacitive energy converters (CEG) with built-in bias voltage. The subsequent implications on the selection of the optimal conditioning circuit are also presented. In particular, the determining role of the application context and constraints on the optimal conditioning circuit choice is discussed. This context is defined by the transducer's capacitance variation amplitude, by the value of the built-in bias of the transducer, and by limitations on the operating voltages across the circuit elements and the transducer.

Abstract. This work is dedicated for the study of energy harvesters implemented in form of microelectromechanical systems (MEMS) used to harvest ambient vibrations for powering standalone electronic devices. The previewed application is to power a leadless pacemaker with mechanical energy of the heartbeat, which requires the amount of power typically more than 1μW. The target of the presented article is to combine the effect of bistability and nonlinear coupling by electrostatic effect in order to achieve the high value of bandwidth at the low frequency under the low accelerations. Such system is expected to bring high power density performance. This study is performed mostly by numerical simulation.For the present day energy harvesting is viewed as a promising and innovative alternative for the batteries in the task of powering a wide variety of standalone devices. The examples could be found in different fields: starting from the infrastructure monitors and sensor networks up to biomedical applications.Conception and design of the energy harvesting device that will be able to deliver >1μW of power under the low frequency excitation (20-30Hz) with acceleration of 1g is in the scope of this work. Such parameters are not very far from the values of the human heartbeat, so the presented device could serve as a starting point in development of the mechanism capable of powering the pacemaker [1]. Numerous examples of the energy harvesters operating with such input parameters had already been proposed, but generally they are not compatible with biomedical applications due to the size [2] and use of magnetic elements [3]. However, introducing the non-linearity in electrostatic energy harvester could produce a dramatic effect on its performance [4].In the bistable system, the switching between stable positions depends only on the value of the external applied force [5], and it could be used to access the low frequencies keeping the bandwidth high for the external excitation.It had been clearly demonstrated that maximum power that can be converted by an inertial power generator is proportional to the operational frequency of the transducer [6]. So, the frequency-up conversion is a promising strategy to increase the output power value. Design of the device and the simulation of its performance is presented in this paper.
