Voice coil motor (voice coil motor) take you to see a lethal portable detector, according to reports, American researchers in a new issue in the journal of the American chemical society, the core scientific report, said they use chemical sensors, lego and smart phones, to create a low-cost portable nerve agent detectors, emergency workers can help quickly identify deadly poison, and take measures to save lives. The team connected chemical sensors to smartphones and installed the device in a "dark box" made of lego bricks. Using non-toxic chemical gas development of simulation test shows that cooperate with ultraviolet light source and test standard 96 hole board, sensor can show different colors for different gas fluorescence, brightness represents the concentration. The smartphone camera is used to capture the fluorescence response of the sensor. After analyzing the image, the software can accurately and quickly determine the type and dose of the simulated neurotoxic agent. The researchers found that lego boxes provide the dark environment needed to capture fluorescent signals. Compared with 3D printing, it is not only light in weight, low in cost and easy to obtain, but also easier to disassemble, assemble and replace parts.
See above, the small make up have to mention the smartphone camera in a lethal portable detector, the use of voice coil motor (voice coil motor) little not, because of the voice coil motor (voice coil motor (VCM) based on the ampere theorem of work, namely when conducting wire coil, the electric current produced by force to push on the carrier with camera movement, so as to change the focus distance. As you can see, the control of the focal distance of the voice coil motor (VCM) device is actually achieved by controlling the current in the coil.
Kunshan is a collection of voice coil motor with alum motor (voice coil motor (VCM) technology research, development, linear motor, voice coil motor (voice coil motor (VCM), precision linear platform smart and sales as one of the manufacturers. The company's products used in the following fields: laser cutting equipment industry, semiconductor equipment industry, flat panel display industry, printing equipment, medical apparatus and instruments industry, precision testing instruments industry, electronic components SMT equipment industry, PCB testing equipment, logistics equipment industry, etc.
