Collapsible, Lockable Tent Microwave Metal Detector

Introducing a revolutionary safety device designed to protect households from microwave-related fires. This innovative system automatically shuts off the microwave upon detecting sparks, addressing the alarming statistic of approximately 7,400 fires caused by microwaves in 2005, leading to 87 injuries and $18 million in property damage. Targeting major microwave manufacturers and Original Equipment Manufacturers (OEMs) like GE and Sharp, this technology holds significant potential within the market, addressing safety concerns for the 13.5 million microwaves sold in the U.S. last year.
