Researchers at Linköping University and the KTH Royal Institute of Technology have developed the world's first transistor made of wood. Their study, published in the journal PNAS, paves the way for further development of wood-based electronics and control of electronic plants.
Transistors, invented almost one hundred years ago, are considered by some to be an invention just as important to humanity as the telephone, the light bulb or the bicycle. Today, they are a crucial component in modern electronic devices, and are manufactured at nanoscale. A transistor regulates the current that passes through it and can also function as a power switch.
Researchers at Linköping University, together with colleagues from the KTH Royal Institute of Technology, have now developed the world's first electrical transistor made of wood.
"We've come up with an unprecedented principle. Yes, the wood transistor is slow and bulky, but it does work, and has huge development potential," says Isak Engquist, senior associate professor at the Laboratory for Organic Electronics at Linköping University.
