PROBLEM TO BE SOLVED: To provide a device, a system and a method, for maintaining temperature of a food after the food is placed on or in a serving wear. SOLUTION: A small and inexpensive wireless temperature sensor sticker 120 is provided for detecting the temperature of the serving wear 121. The temperature sensor sticker generates a magnetic field of the size sufficient for bringing a re-magnetizing response of a temperature sensor element and an optional data element to detect such a response, and a micro wire reader/detector 136 can be used in combination, which can measure the temperature of the serving wear by a decoding algorithm with the use of the detected response. The temperature sensor sticker can be used in a closed loop heating system capable of controlling heating of the serving wear. COPYRIGHT: (C)2013,JPO&INPIT |
