Technology overview

MEMS

Micro-Electro-Mechanical Systems, or MEMS, is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of microfabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters. Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics. The one main criterion of MEMS is that there are at least some elements having some sort of mechanical functionality whether or not these elements can move.

ASIC

An application-specific integrated circuit (ASIC) is a kind of integrated circuit that is specially built for a specific application or purpose. Compared to a programmable logic device or a standard logic integrated circuit, an ASIC can improve speed because it is specifically designed to do one thing and it does this one thing well. It can also be made smaller and use less electricity. The disadvantage of this circuit is that it can be more expensive to design and manufacture, particularly if only a few units are needed. An ASIC can be found in almost any electronic device and its uses can range from custom rendering of images to sound conversion. Because ASICs are all custom-made and thus only available to the company that designed them, they are considered to be proprietary technology.

sensor hub

Sensor Hub is a microcontroller unit/coprocessor/DSP that helps to integrate data from different sensors and process them. With the increase of smart phone, wearable device and sensor integrated by sensing terminal of internet of things, and applications require sensors to be "Always On", which makes low-power Sensor Hub more and more important. This technology can help off-load these jobs from a product's main central processing unit, thus saving battery consumption and providing a performance improvement.
