Thread-Based Transistors Flex without Damage

Thread-Based Transistors Flex without Damage
Transistors and electronics made from thread could help pave the way to fully flexible and functional electronic devices.

Developed by a team from Tufts University, the thread-based circuits are made up of a linen thread that has been coated with carbon nanotubes to create a semiconductor surface. A pair of attached thin gold wires function as the source and drain for the electrodes, along with a third wire attached to the surrounding material that acts as the gate. According to the team, a key innovation in the technology was the electrolyte-infused silica nanoparticle gel surrounding the thread and connected to the gate wire, which can be easily applied to the thread and remains intact even during stretching and flexing.
