    Check it Sony, 'cause if necessity is the mother of invention then you're about to be calling the ETRI daddy. Coming a bit too late for some, ETRI (Telecommunications Research Institute of Korea) have developed what they call a Critical Temperature Switch to prevent exploding batteries in mobile devices. Smaller, but more reliable than ceramic sensors, the new switches use a Mott Metal-Insulator Transistor or MIT, to prevent batteries from swelling and exploding in a violent discharge triggered by overheating. Ultimately, ETRI expects to integrate over 16,000 of the Critical Temperature Switches or 5,000 explosion-proof systems into a film just 2-inches in diameter. For the time being, they are looking for partners to develop their commercially ready technologies into product. Hey Sony, you paying attention?
