The World Of Microscopic Machines

The World Of Microscopic Machines
Micro-electromechanical systems or MEMS are tiny integrated devices that combine mechanical and electrical components. Traditional manufacturing techniques such as milling, turning, and molding become impractical at small scales so MEMS devices are fabricated using the same batch processing techniques used to fabricate integrated circuits. These devices can range in size from a few microns to several millimeters.
Because MEMS devices are a hybrid of mechanical and electronic mechanisms, they’re generally fabricated using a combination of traditional integrated circuit technologies and more sophisticated methods that manipulate both silicon and other substrates in a manner that exploit their mechanical properties.
In bulk micromachining, the substrate is removed in a manner similar to traditional integrated circuit techniques.
Surface micromachining, by comparison, is a predominantly additive in nature and is used to create more complex MEMS-based machinery. Material is deposited on the surface of the substrate in layers of thin films.
High-aspect-ratio micromachining differs dramatically from the other two techniques in that it’s reminiscent of traditional casting.
The accelerometers used in automotive airbag sensors were one of the first commercial devices using MEMS technology. In widespread use today, they measure the rapid deceleration of a vehicle upon hitting an object by sensing a change in voltage. Based on the rate of this voltage change, the on-die circuity subsequently sends a signal to trigger the airbag’s explosive charge.
In most smartphones, a MEMS-based gyroscope complement the accelerometer. They’re also found in navigation equipment, avionics and virtually any modern device that requires rotation sensing. MEMS gyroscopes work by suspending an accelerometer on a platform that in itself uses a MEMS-based solenoid to create a constant oscillating motion.
Another hugely successful application of MEMS technology is the inkjet printer head. Inkjet printers use a series of nozzles to spray drops of ink directly on to a medium. Depending on the type of inkjet printer, two popular MEMS technologies are used to accomplish this; thermal and piezoelectric.
DLP
One of the earliest uses of MEMS devices in the form of large mechanical arrays on a single-die has been for display applications. Invented by Texas Instruments. Each pixel is made of a multi-layered device consisting of an aluminum mirror mounted on hinges. These pixels rest on a CMOS memory cell.
Digital micromirror devices form the basis for another emerging application of MEMS technology, electro-optics. These bottlenecks can be eliminated by using fully optical networks that offer far superior throughput capabilities.

One of the more promising applications of MEMS technologies has been the emergence of biomedical MEMS devices. Referred to as Bio-MEMS devices, they tend to focus on the processing of fluids at microscopic scales.
One of the first and simplest examples of a bio-MEMS device is the micro=machined microtiter plate. A microtiter plate is a flat plate with multiple wells used as small test tubes for testing and analysis.
The possibilities with MEMS devices are astounding. Applications from low-loss, ultra-miniature and highly integrated tracking radio antennas to sensors that can measure heat, radiation, light, acoustics, pressure, motion and even detect chemicals.

  • I had no idea that nanotechnology was anywhere near this level! We're truly becoming that mysterious "alien" race with all the scary technology we've read about in sci-fi books. The future is being defined by our best and brightest engineers, and this makes me feel like I'm still in the Bronze Age. The most concerning part, is our paranoid nature ensures that technology will continue to become our master, and that genie is already out of the bottle.

  • "And costs several hundreds of dollars" Modern airbags are stupidly expensive not to mention the damage they do to the car. many cars with multiple airbags (over 2) will be totaled if they go off.

    • @Mi 28 Roll cages, multipoint harnesses, helmets, and HANS devices.(inconvenient for standard vehicles). Lot of accidents on the race track don't have an impact at high speed and their cars weigh less (less energy at impact) due to sand traps or energy absorbing walls (Spring or tires). Civilian cars have to balance luxury (weight and convenience) and the sometimes accumulative collision of 2 speeds.

    • Airbags exist because people still don't use seatbelts. No racing car uses these despite being subject to frequent crashes at blistering speeds, they did their math and figured airbags are worthless.

  • I wonder how the idea came up? Johnathan: wait what happend if we make machines but there microscopic. Tyler: enough with your bullshit John every day you do this. Every fkin day and I'm sick of your shit. When are you going to realised that your ideas are stupid when are you going to realised that you need to do actually research to feed your family. Your the reason why Karen took the kids John. You are!! Johnathan: your done being a bitch? Okay let's do this.

  • 2:10 the wafer itself is a slice (literally a wafer) of monocrystalline silicon. it is not coated in silicon. you also got your labelling of positive/negative photoresist exactly backwards. upon UV exposure, a positive PR will wash away during development while a negative PR becomes insoluble. the way to remember it is that after exposure and development, a positive PR becomes a copy of the UV mask, while a negative PR becomes the negative copy of the UV mask. in traditional film photography the light exposed parts precipitate silver and become insoluble to developer so the lightest part of the picture is the darkest (that's why developed film is called a negative). also doping is not done through oxide. that is etched off first.

If you are up for it, even getting in touch with a top academic in the field with 5-10 questions would be a welcome addition. Keep it up mate.
