A wink can turn the light on
Chongqing, Aug. 4 (xinhua) -- can you turn on the lights and transmit information? The latest scientific research from chongqing university makes the scene in these science fiction movies become reality. By professor hu fruit chan at chongqing university physics college team and the Chinese academy of sciences academician wang and others together to complete the research papers of the electricity generation by using friction of nano technology construction of eye movement triggers from drive sensory control the human-computer interaction system ", recently in the journal science progress international authoritative academic journal. The scientific research team has designed the use of the sensory control human-computer interaction system, the friction nano power generation technology sensor, and has also passed the verification of many application tests.
The first author of the paper, pu xianjie, a doctoral student at chongqing university, demonstrated the application of this technology. She was wearing a glasses frame on the sensor, blink of an eye the transmission of signals through the sensor, filter, amplifier and a series of receiver, not only can control the switch of electronic equipment, and can use the cursor move output accurate English words and the blank space symbols. PuXianJie said, it's a very simple sensor production materials, production costs only 1 yuan, but the sensitivity is extremely high, typing output success rate reached 94.5%, is very beneficial to popularization and application in the future.
Hu said the biggest breakthrough in the research was the first application of friction nano-power technology in the field of human-computer interaction. The traditional capacitive sensor mainly USES bioelectricity to control the human-computer interaction system, the signal is weak, and it is easily weakened by the noise. The new sensor, developed by the chongqing university research team, is controlled by a self-drive that causes tiny movements in the skin in the blink of an eye, and the signal is 750 times the capacity of the capacitor. According to hu, this research has realized the use of the senses to communicate with the outside world, which will greatly promote the development of artificial intelligence.
