A REMARKABLE electronic circuit made entirely from the cells of an LCD display has been created using software that mimics evolution’s drive for fitness. By reorienting the liquid crystals in individual cells, the software can transform a display into a circuit that can distinguish between high and low-frequency signals, without using any conventional electronic components like transistors, capacitors or resistors.
The circuit was developed by electronics engineers Simon Harding and Julian Miller at the University of York in the UK. It emerged from an experiment aimed at discovering whether a genetic algorithm (GA) – software that mimics natural selection to…
