A method of detecting a stimulus can include detecting an output from a radio frequency identification tag including a sensor. A smartphone-based sensing strategy can use chemiresponsive nanomaterials integrated into the circuitry of commercial Near Field Communication tags to achieve non-line-of-sight, portable, and inexpensive detection and discrimination of gas phase chemicals (e.g., ammonia, hydrogen peroxide, cyclohexanone, and water) at part-per-thousand and part-per-million concentrations.

Methods described herein may be useful in the fabrication and/or screening of devices (e.g., sensors, circuits, etc.) including conductive materials. In some embodiments, a conductive material is formed on a substrate using mechanical abrasion. The methods described herein may be useful in fabricating sensors, circuits, tags for remotely-monitored sensors or human/object labeling and tracking, among other devices. In some cases, devices for determining analytes are also provided.
