1. A system for detecting a stimulus comprising:
a radio frequency device comprising a sensor element comprising an integrated circuit and a first resistive element, wherein the sensor element comprises a material responsive to an analyte and which is configured to elicit a response when a stimulus contacts or interacts with the radio frequency device; and
a portable reader adapted to
transmit radio frequency waves to the radio frequency device;
receive a spectrum of radio frequency waves from the radio frequency device; and
relate a characteristic of the spectrum to a concentration of the analyte,
wherein the characteristic of the spectrum comprises a gain of the radio frequency device and/or a reflected attenuated signal of the radio frequency device.
