ABSTRACT:
A sensing system, sensing method, and method of producing a sensing system capable of providing a cumulative measurement capability, such as in the form of a RFID tag capable of measuring cumulative heat and humidity for continuous monitoring of storage and shipping conditions of various goods. The system includes integrated circuitry and a plurality of sensing elements, preferably having cantilevered bimorph beams. Each sensing element is responsive to an environmental condition so as to deflect toward and away from open contacts in response to changes in the environmental condition. Each sensing element produces a digital output when it contacts and closes its open contacts. The integrated circuitry interfaces with the sensing elements so that the digital outputs of the sensing elements are processed to generate a system output of the sensing system.
