摘要： A sorbent product having a sensor array for detecting a sorbate. The sorbent product includes a sorbent body configured to absorb the sorbate and a sensor array integrated with the sorbent body. The sensor array includes a plurality of sensing elements, an electric power source in electrical communication with the plurality of sensing elements, and a controller configured to detect a change in an electrical property of at least one of the plurality of sensing elements and provide a signal containing information based on the detected change.

摘要： A sensor product for detecting an analyte or condition. The sensor product having a body and a circuit integrated with the body. The circuit including an electric power source, a sensing element comprising graphene or a graphene derivative in which the sensing element is configured to undergo a change in an electrical property in the presence of an analyte or condition, and an indicator configured to display information indicating the presence of the analyte or condition when the change in an electrical property of the sensing element occurs. For instance, the indicator may display “DANGER EVACUATE” in the presence of chlorine gas, elevated temperatures, or other analytes or conditions.

摘要： A label adapted to be attached to an item and a system for validating a label are provided. The label contains an identifying portion of a circuit path extending between at least a pair of contact points in which the identifying portion of the circuit path includes a segment containing graphene. The system can include this label and a validating device. The validating device includes a testing portion of the circuit path adapted to contact the at least the pair of contact points of the identifying portion of the circuit path in the label to thereby complete the circuit path. The testing portion of the validation device is configured to internally process and validate the label in the validating device.
