Wireless Device and Topologies for Energy Harvesting Based on Maxwell Displacement Current

Hub APTA Background
Current energy efficiency and demand have an important role to play now that global energy prices are high and volatile, hurting homes, industries, and entire economies. Energy efficiency becomes the protagonist to reduce energy costs and dependence on imported fuels, generating important environmental, economic, and social benefits. When seeking to achieve levels of energy efficiency for sustainable progress, the optimization of operation and maintenance processes becomes necessary.
Technologies such as the Internet of things, ultra-low power embedded systems, 5G wireless communication, and wireless sensor networks allow establishing adequate connectivity between agents that make up a power system. However, many sensors are required to guarantee data collection processes and communication reliability, because, although these devices have high power densities, the large capacitive input impedances restrict the output power.
As a solution to this problem, nanogenerators based on the Maxwell displacement current have been developed that integrate additive manufacturing capabilities for the development of new topologies with new cutting-edge dielectric materials, thus increasing the available power.
Technology Overview
The technology is formed by the first layer of dielectric material surrounding the first portion of the conductor line; the second layer of a conductive material surrounding the aforementioned dielectric material; a metallic plate connected to the ground; a rectifier circuit having two inputs and two outputs and to whose outputs a capacitor is connected. In addition, it contemplates the third layer of a conductive material that surrounds a second portion of the conductive line; a switch that connects the second layer with the metallic plate, and, finally, a voltage comparator operatively connected to the switch and the third layer of conductive material, being this comparator the one that controls the switching state.

Easy to manufacture.
Its design does not present any mechanical difficulties, making it a significant improvement over current technology.
This project introduces nanogenerators based on Maxwell displacement current.

It is applicable to many current known technologies such as the Internet of Things, ultra-low power systems, 5G wireless communication and wireless sensor networks that allow establishing a proper connectivity between agents that make up a power system.
It is in this specific field where the invention allows powering such systems, thus meeting the requirement of many sensors to ensure data collection processes and communication reliability.
The university are looking for an opportunity to find an interested co-developer and/or licensee of the technology with the objective of commercial use of the technology.
