Ambient RF Energy Harvesting Technology and its Applications
— This paper is focused on equipping wireless devices (including sensors) with novel, high efficiency circuitry to harvest and convert ambient RF power to direct current (dc). Key components of this technology are (a) miniaturized antenna and (b) high efficiency rectifying circuit. The first is responsible for capturing the RF waves, and the latter coverts the RF energy to dc. A major challenge...
متن کاملOn energy harvesting from ambient vibration
Future MEMS devices will harvest energy from their environment. One can envisage an autonomous condition monitoring vibration sensor being powered by that same vibration, and transmitting data over a wireless link; inaccessible or hostile environments are obvious areas of application. The base excitation of an elastically mounted magnetic seismic mass moving past a coil, considered previously b...
متن کاملEnergy harvesting – small scale energy production from ambient sources
Energy harvesting – the collection of otherwise unexploited energy in the local environment – is attracting increasing attention for the powering of electronic devices. While the power levels that can be reached are typically modest (microwatts to milliwatts), the key motivation is to avoid the need for battery replacement or recharging in portable or inaccessible devices. Wireless sensor netwo...
متن کاملEnergy Harvesting Technology for Maintenance-free Sensors
Energy harvesting is a technology that gathers energy such as sunlight, artificial light, and vibration and heat from machinery to obtain electric power. Applying this technology to wireless sensor modules in a machine-to-machine (M2M) wireless sensor network will eliminate the need for grid-based power and primary batteries and create new value in the form of maintenance-free, battery-free, an...
متن کاملOptimal Energy Transfer in Light-Harvesting Systems.
Photosynthesis is one of the most essential biological processes in which specialized pigment-protein complexes absorb solar photons, and with a remarkably high efficiency, guide the photo-induced excitation energy toward the reaction center to subsequently trigger its conversion to chemical energy. In this work, we review the principles of optimal energy transfer in various natural and artific...
