Under the combined action of the gold nanoparticles and the cavity, the directional high-frequency ultrasound drives the dispersion to generate high-speed flow through the acoustic wave driving effect. Wang Zhiming also said that once the microcavity is formed, the gold nanoparticle dispersion can be replaced with pure water or other solutions, and the laser pointer can also drive other liquids to flow.
The success of this test indicates that light can drive the movement of macroscopic matter, which is different from other elements in nature. In laser-driven fluid technology, light is a controllable element, which has made it possible to control the laser of fluids from the micron level to the centimeter level. The results of this experiment may be applied to microfluidic systems and even wearable portable medical devices.
The rapid development of automotive technology has accelerated the iteration of automotive technology, and some new technologies and products have emerged from this, such as biometrics. The so-called biometric technology refers to a technology that uses human biometrics for identity authentication. These biometrics usually include fingerprint recognition, iris recognition, retinal recognition, facial recognition, DNA recognition and other unique, can be measured or automatically identified and verified, Hereditary or life-long characteristics. Among them, fingerprint recognition and facial recognition have been applied to self-driving cars, and biological green laser pointer sensors have also been derived from this.
