Abstract: A problem is endangering American soldiers all over the world. Heavy individual batteries and restrictive cables are known to encumber a soldier's mobility in combat situations. This project aims to determine the feasibility of a wireless, centralized power system that has the potential to free soldiers from wires and individual batteries, thereby improving their efficacy on the battlefield. A wireless power system designed to supply the electronics carried by a soldier, should have a range of approximately 30cm. Additionally, the system must be cost effective, efficient, lightweight, and reliable. Our company has previously created a wireless power technology that can supply energy to handheld electronics over a short distance. WiPower has spent four years researching the most efficient way to transfer power across a range of less than 1 cm. Current methodologies allow our wireless system to perform similarly to a conventional corded power supply. Our prior research indicates that our technology is a high potential candidate to meet the needs of soldiers. The research conducted during Phase I will determine the feasibility of a 30 cm range for WiPower technology. If this range is achieved, soldiers and vehicles could be equipped with wireless power in the near future.
Benefits: WiPower technology has the potential to reach a $5B annual market. The consumer electronics market represents 1.33 billion units per year and each device requires a power supply that must be plugged into the device in order to transmit power. Consumers want to cut the last cord and never have to plug their device in again. Wireless Power transmitters will be integrated into airports, cafes, home desktops and many other applications, effectively letting consumers power their electronics everywhere they go.
