Wooden Transistor: A Groundbreaking Invention
Researchers from the Wallenberg Wood Science Center have created the world's first wooden transistor, which is 3 centimeters across and switches at less than one Hertz. The transistor holds promise for specialized applications including biodegradable computing and implanting into living plant material. The researchers leveraged the structural stability and porosity of balsa wood to create conducting channels inside the wood's pores and electrochemically modulate their conductivity with the help of a penetrating electrolyte and a conducting polymer.
