World’s First Electric Wooden Transistor Invented by Scientists:
Researchers from Linköping University and the KTH Royal Institute of Technology have achieved a major breakthrough in the field of sustainability and efficiency by creating the world’s first wooden electrical transistor. In a press release issued on Thursday, the institutions announced that they have developed an innovative principle that could pave the way for significant developments in the future. Although the wooden transistor is currently slow and large, it functions effectively and has tremendous potential for development, according to Isak Engquist, senior associate professor at Linköping University’s Laboratory for Organic Electronics.
Previous attempts to create wooden transistors had only resulted in versions that could control ion transport. These earlier transistors also failed to function once the ions ran out. However, the new wooden transistor developed by the researchers can continue to control the flow of electricity without degradation. The balsa wood used to create the device plays a crucial role in this regard, as the technology demands a wood with a uniform grain throughout.
To make the wooden transistor, the researchers removed the lignin from the wood, leaving behind only long cellulose fibers with channels where the lignin had been. They then filled these channels with a conductive plastic or polymer called PEDOT:PSS, resulting in an electrically conductive wood material.
