"Conductive paint", as the name suggests, is a paint that can conduct electricity. If the technology is mature, its application prospects will be very broad. This circuit board designed by a London design team is a good example of the application of "conductive paint". He turns the conductor surface into a sensor and builds a simple audio touch platform with speakers, batteries and SD cards. The short-range air sensor characteristics (within 20 centimeters) and touch sensors allow interactive devices such as paper musical instruments and hidden alarms to be realized. I won’t say more, let’s watch the video.
