In an experiment, the researchers created a touch sensor consisting of a simple nanomesh conductor array applied to a fingertip. The resistance between the nanomesh conductor strips decreases when a conductive object creates a shortcut. Such electrode arrays were also used to create a thermal and a pressure sensor, by applying a strip of positive temperature coefficient (PTC) polymer and pressure-sensitive rubber across them, respectively.
In another implementation, the nanomesh conductors were used as on-skin electrophysiology electrodes for electromyography (EMG) recording and yielded good signals comparable to today's gel electrodes.
The researchers also tested a gold nanomesh skin patch for one week to prove the breathability and the very low risk of skin-inflammation, recording electromyograms with minimal discomfort to the user.
