Sensor of transparent electrode dactylogram comes out the new method that implements the dactylogram below screen

England " natural · communication " the magazine published new breakthrough of science of a material recently: The structure of rice of accept of random mixing network that Korea scientist group uses fiber of rice of silver-colored accept of train in excess specified length and group of rice of pure silver-colored accept to become, innovation goes new-style and transparent electrode, produce a kind of transparent dactylogram sensor then. On smartphone screen demonstrate to make clear, this kind of sensor can let an user put finger in any positions of screen to undertake the identity identify, and do not need to use dactylogram activation button.

Dactylogram sensor is the crucial parts of an apparatus that dactylogram of electronic equipment implementation collects automatically. Its need to be not worth 0.5 square in centimeter chip surface is compositive the semiconductor of 10000 above sends feeling unit, accordingly although dactylogram is collected very common already now, but the production of dactylogram sensor still belongs to omnibus strong, technology is sophisticated the new and high technology with degree of tall, bad workmanship.

Sensor of transparent electrode dactylogram comes out the new method that implements the dactylogram below screen

Consumptive electron market goes after transparent dactylogram sensor energetically all the time. Nevertheless, the skill that shows level accepts the design restriction with decisive be confined to, need development to issue bright to transmit for instance with the transparent electrode with tall function of electronic electric conduction. And this, the scientist rolled out the dactylogram sensor array of production smartphone eventually, these array are OK and synchronous detect tactile pressure and finger skin temperature.

Group of scientist of institute of state-maintaineding science and technology of Korea colourful hill devised a kind of new method, will make flexible and transparent multi-function transducer array. The recipe of this design depends on a basis the structure of rice of accept of random mixing network that by silver of train in excess specified length group of accept rice fiber and rice of pure silver-colored accept becomes, innovation goes new-style and transparent electrode.

This kind of mixing network shows higher smooth transmission power and low resistance, extremely be able to bear or endure mechanical turn is folded. After blending in its dactylogram sensor array, get plant of a high resolution, can accurate and reliable ground detects the backbone cereal region that feels the dactylogram below the condition.

Array of sensor of research group grain middling finger, pressure quick transistor and temperature sensor are compositive display screen to the smartphone, lend the applicable that this revealed this new technology to go up in mobile equipment the gender. This also is meant, hopeful of this kind of sensor replaces dactylogram activation pushbutton in future.
