Abstract: A computer-implemented method of automated design for a vibration-based energy harvesting system for a host structure includes receiving acceleration signals obtained from one or more accelerometers attached to the host structure, determining dominating acceleration frequencies of the host structure from the received acceleration signals, determining a degree-of-freedom number of a cantilever beam based on the number of dominating acceleration frequencies of the host structure, simulating vibration of the cantilever beam across a plurality of parameters, determining values of the plurality of parameters that result in a match between resonant frequencies of the cantilever beam and the dominating acceleration frequencies of the host structure, and outputting a proposed design of the cantilever beam including the values of the plurality of parameters.

Abstract: A partially magnetized pavement is placed above a transmitter coil for improved efficiency of electric vehicles charging through wireless power transfer. The partially magnetized pavement includes a non-magnetized pavement portion positioned vertically above the transmitter coil and a magnetized pavement portion positioned vertically above a first area surrounded by the inner dimension of the transmitter coil and a second area outside the outer dimension of the transmitter coil. In some cases, the partially magnetized pavement further includes a transmitter coil having the inner dimension and the outer dimension and a capacitor electrically coupled to the transmitter coil to form a resistor-inductor-capacitor circuit at a system level. In some cases, a plurality of electric vehicle charging units are positioned in a center of a lane in a roadway and separated from one another by a predetermined distance along a direction of the lane in the roadway.
