Abstract
A smart label includes an antenna and an integrated sensor, and in response to receiving an initiating interrogation signal transmits a response signal that includes a first component that identifies the smart label and second component that provides data generated at the sensor in response to an environmental parameter. The response signal allows the data indicating the status of the environmental parameter, such as temperature or moisture, at the location of the specific smart label to be transmitted along with a time stamp. A method of activating a sensor on the smart label is also provided.
Claims20
A smart label, comprising:
- a substrate;
- an electrical circuit affixed to substrate, the electrical circuit comprising:
- a receiver configured to receive an interrogation signal and transmit a response signal;
- and
- a sensor configured to monitor an environmental parameter and to generate a data component indicative of a characteristic of the environmental parameter, wherein the response signal comprises the data component.
A smart label, comprising:
- a flexible substrate;
- an electrical circuit affixed to the flexible substrate, the electrical circuit comprising:
- a sensor configured to generate a data component in response to an environmental parameter;
- an antenna configured to receive a radio frequency interrogation signal and transmit a radio frequency response signal in response to receiving the radio frequency interrogation signal, the radio frequency response signal comprising the data component and a smart label identification component configured to identify a value of interrogation signals received at the smart label;
- and
- wherein the electrical circuit is configured to receive a power supply from a signal received by the antenna.
A method of activating a sensor on a smart label, comprising the steps of:
- transmitting power from a signal received by an antenna to an electrical circuit affixed to a substrate, wherein the electrical circuit comprises the sensor and the antenna;
- receiving an interrogation signal at the antenna;
- and
- activating the sensor to generate a data component in response to receiving the interrogation signal.
