They attain medium data transfer speed, sufficient for applications like electroencephalography. The majority of opto-isolators on the market use bipolar silicon phototransistor sensors. Commercialization of LED technology in 1968–1970 caused a boom in optoelectronics, and by the end of the 1970s the industry developed all principal types of opto-isolators. They are the slowest, but also the most linear isolators and still retain a niche market in the audio and music industries. Photoresistor-based opto-isolators were introduced in 1968.
