Chemoelectronics: Nanoparticle Diodes and Devices That Work When Wet – IEEE Spectrum

Whether they’re for sensors in artificial skin that demands flexibility or for wearable electronics where the circuits must withstand our sweat, silicon-based chips aren’t always up to the task.

Now, an international research team has developed a way to fabricate flexible, water-loving logic circuits and sensors without the need of semiconductors. Instead, what the researchers have done is coat gold nanoparticles with charged organic molecules to create a system that they’ve dubbed a “chemoelectronic circuit”.
