A periodic folded piezoelectric beam for efficient vibration energy harvesting
Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...

متن کاملRF Energy Harvesting System And Rectennas
Recent advances in ultra-low power wireless communications and energy-harvesting technologies have made self-sustainable devices feasible. Typically, the major concern for these devices is battery life and replacement. Applying energy harvesting techniques to these devices can significantly extend battery life and sometimes even eliminate the need for a battery. This technique is widely applica...
متن کاملEfficient Broadband RF Energy Harvesting for Wireless Sensors
This paper presents an approach to wireless power delivery and subsequent power management for low-power batteryless sensors. Broadband multifrequency rectenna arrays which independently receive and rectify two orthogonal wave polarizations provide DC power with decreased variations in a multipath environment. The DC power extracted from 2-18GHz electromagnetic radiation is managed by high effi...
متن کاملTransmission Power and Antenna Allocation for Energy-Efficient RF Energy Harvesting Networks with Massive MIMO
The optimum transmission strategy for maximizing energy efficiency (EE) of a multi-user massive multiple-input multiple-output (MIMO) system in radio frequency energy harvesting networks is investigated. We focus on dynamic time-switching (TS) antennas, to avoid the practical problems of power-splitting antennas, such as complex architectures, power loss and signal distortion when splitting the...
