This paper studies the simultaneous wireless information and power transfer (SWIPT) in the multi-carrier differential chaos shift keying (MC-DCSK) communication system. Two energy harvesting protocols with a power splitting (PS) receiver are considered. In the first protocol, only a fraction of reference sub-carrier signal are used for energy harvesting (EH). In another one, a fraction of all sub-carriers...
Energy harvesting is an increasingly attractive source of power for wireless communications devices. Microwave power transfer (MPT) delivers energy from power stations (PSs) to mobile users by microwave radiation. In this paper, we consider a network architecture where PSs are distributed in an uplink cellular network for powering mobile users. MPT transmits power to mobile devices adaptively. Transmission...
Two new fields are introduced to MEMS/NEMS: a nanogenerator that harvests mechanical energy for powering nanosystems, and strained induced piezotronics for smart MEMS. Fundamentally, due to the polarization of ions in a crystal that has non-central symmetry, such as ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a stress. The principle of harvesting...
Summary form only given. Developing wireless nanodevices and nanosystems is of critical importance for sensing, medical science, environmental/infrastructure monitoring, defense technology and even personal electronics. It is highly desirable for wireless devices to be self-powered without using battery. This is a new initiative in today's energy research for mico/nano-systems in searching for sustainable...
