We investigated the variations in the magnetic field distribution and power transmission efficiency, resulting from changes in the relative positions of the transmitting and receiving coils, for electromagnetic induction-type wireless power transmission using an elliptical receive coil results of simulations using a high-frequency structure simulator were compared to actual measurement results. Transmission of sensor data for monitoring use of the gprs of telecommunications company the wireless sensor network (wsn) technology penetrated from the field of military reconnaissance to indus- trial areas in recent years, which became the most popular areas of wireless networks.
Wireless power transfer to ground sensors using a uav (quadrotor) the paper is titled, resonant wireless power transfer to ground sensors from a uav ( pdf ) by brent griffin and dr carrick detweiler. The application is primarily designed for the wireless sensor networks, as the sensors are low consumed power and at the same time energy constrained but the similar analogy can be established into the other charging systems for the rat- fig 3: conceptual model of wpt in wsn. Fig 1: photograph of the microwave power and data transmission system (a) wireless power transmission using one transmitting antenna and receiving antenna (b) two wireless sensor nodes with strain gauges (c) base station with a distance of 50 meters away from the sensor nodes (d) schematic of a rf-powered wireless sensor node.
Wireless power transfer to ground sensors using a uav (quadrotor) the paper is titled, resonant wireless power transfer to ground sensors from a uav surface based wireless power transmission and bidrectional communication for autonomous robot swarms (pdf and presentation slides. In particular, this paper details the transfer of power over the microwave band, called microwave power transfer or microwave power transmission (mpt) other approaches to wpt include magnetic field resonance and capacitance, and are mentioned in this paper for completeness as alternative methods for wpt. We have many power chargers for many electronic devices too many chargers and cables a traveler knows the pain of carrying all these chargers standardized usb charging connector is a solution but there are still proprietary connectors/chargers wireless power is the ultimate solution – cut the last cable.
