Biodegradable electronic display designed to help minimize e-waste


Manuel Pietsch, KIT
E-waste is a growing problem, so if an electronic component can't be reused or recycled, it should at least be biodegradable. That's where an experimental new electronic display comes in, as it can be composted when no longer needed.
Created by scientists at Germany's Karlsruhe Institute of Technology (KIT), the device is a type of electrochromic display. It utilizes an organic polymer known as PEDOT:PSS, in which the amount of light absorption changes as voltage is applied – as a result, individual segments of the display change between almost-clear and opaque states.
That polymer is deposited on a cellulose di-acetate substrate and sealed in an electrolyte gelatine, making the display both flexible and adhesive. The electrical current is applied via gold electrodes. And like other electrochromic displays, this one can be inexpensively produced using an inkjet printer.
