The world’s first wooden transistor has been created by researchers from Linköping University and the Royal Swedish Institute of Technology, reports Prensa Latina on April 29.
The researchers used cork wood to build their transistor. They removed the lignin, leaving only long ribbed cellulose fibers, which they then filled with a conductive plastic or polymer called PEDOT:PSS, resulting in an electrically conductive wood material.
The transistor, developed by the Linköping researchers, can operate continuously and regulate the flow of electricity without degrading performance. It could also turn it on and off, albeit with a slight delay: turning it off took around a second and turning it on took around five seconds.
One advantage of such a large transistor channel is that it can potentially handle higher current than conventional organic transistors, which may be important for some future applications.
The transistor is an essential component of modern electronic devices. The developers admit that the wooden transistor has disadvantages: it is slow and bulky. However, according to them, this development has great development potential.
