All computers, a concern . recent exception of quantum computers, might depend on switches for logic. Those switches — transistors the particular case modern day computers — can be either on or off and form logic gates. All logical operation a computer takes is dependent on the states of those transistors. Traditionally, somewhere between thousands and billions of transistors are put on a rigid silicon wafer establish a pick. But now a team of researchers from Tufts University have built transistors into flexible thread.

This transistor thread could, theoretically at least, be used to create wearable computers. Most wearable technology today contains IC components, such as microcontrollers, usually are embedded somewhere on gadget. The general focus recently been on making those no more than possible solution to to make wearable devices comfortable. But imagine if your t-shirt itself could donrrrt processor. Instead of trying match a rigid microcontroller somewhere on the shirt, the shirt could be packed full of transistor logic gates in order to process operations itself.

To generate the thread, the team started by winding two thin, gold wires around a linen suture. Those wires act as the source and drain electrodes of just a transistor. Then they applied a semiconducting means to the thread, which coats the wires and is absorbed into the linen suture. After the solution’s solvent evaporated, it left behind an even layer of semiconductors around thread. To form the transistor’s gate electrode, they placed a dab of a material called ionogel between the source and drain wires. An additional gold wire was inserted into the ionogel produce a the gate electrode. For now, the transistor wires have for you to become wound together by relinquish order setting their state and perform standard logical operations, but it surely could be possible increase on that in the future.
