Thread Based Transistor (image) Tufts University Share Print E-Mail Caption Top and cross-sectional views of thread based transistor. Source (S) and drain (D) wires are tied to carbon nanotube coated thread, dipped in an electrolytic gate gel. A gate wire is connected to the gel to trigger flow of electrons through the transistor when the gate is above a threshold voltage.
