JonDeTech has been granted a patent for the function of measuring temperature on a surface. This can, for example, be useful for overheating alarms for mobile phone chargers and similar products. The patent applies in Sweden to the use of an open sensor element which is neither encapsulated nor equipped with a lens. JonDeTech's 0.17 mm thin sensor is made of nanowires that are produced in a porous plastic. The sensor element is robust and durable even without encapsulation and can, therefore be placed in an application completely open and yet be an effective solution. The patent is JonDeTech's second application patent. The company will evaluate possible patent protection in other important markets.
