Abstract

An ultra-thin film wireless label can include a temperature sensor. The wireless label can be attached to an object, and the wireless label can be used as a temperature monitoring device. The wireless label can have a stacked structure laying the temperature sensor to have efficient thermal contact with the object, while being relatively insulated from the environment via an insulating layer. The temperature sensor can be calibrated, and the calibration parameters can be stored and used to generate accurate temperature readings. The calibrated wireless label can be used in a variety of applications, including performing battery-saving operations, detecting open-box events, and monitoring temperature of items stored in subzero environments. Some embodiments include activating a wireless label, during a printing process.
