Researchers Turn Transistors Into Thread for Wearable Computing
Public Group active 2 years, 11 months agoAll computers, without the pain . recent exception of quantum computers, might depend on switches for logic. Those switches — transistors the particular case of contemporary computers — can be either on or off and form logic gates. Almost every logical operation a computer takes will depend on the states men transistors. Traditionally, somewhere between thousands and billions of transistors are put on a rigid silicon wafer to create a brand. But now a team of researchers from Tufts University have built transistors into flexible bond.
This transistor thread could, theoretically at least, use to create wearable computers. Most wearable technology today will depend on IC components, such as microcontrollers, usually are embedded somewhere on the device. The general focus has been on making those no more than possible in order to make wearable devices comfortable. But imagine if your primary t-shirt itself could donrrrt processor. Instead of trying to fit a rigid microcontroller somewhere on the shirt, the shirt could be packed regarding transistor logic gates to get able to to process operations itself.
To help make the thread, the team started by winding two thin, gold wires around a linen suture. Those wires be the source and drain electrodes within the transistor. Then they applied a semiconducting in order 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 upon the thread. To form the transistor’s gate electrode, they placed a dab of a cloth called ionogel between supply and drain wires. A third gold wire was inserted into the ionogel to create the gate electrode. For now, the transistor wires have to be wound together by hand in order to set their state and perform standard logical operations, but it surely could be possible increase on that in earth.
