Researchers at the University of Linköping (Sweden) have developed a working analog transistor in which almost all components are derived from wood. Its functional qualities leave much to be desired, switching off occurs within a whole second, and switching on and twice in five seconds. But it works, with its help you can control the flow of electrons – and this is the main thing.
The authors of the study honestly admit that they made this device out of scientific interests, simply because they could. It is actually a by-product of the development of a new wood-based conductive material. A living tree, due to the high moisture content inside, is a conductor, but a high one already becomes dielectric. Therefore, the need to remove lignin from dry wood was checked, and the remaining voids in the form of channels were filled and produced by PEDOT:PSS polymer.
The main advantage is that all components of the transistor are easily decomposed, which is the key to the accumulation of debris in nature. Also, to test the ball with different parameters, tests are carried out in organic materials. Theoretically, the design could just as well be better than any electronic circuit. purposes.
