Micro-Electro-Mechanical systems in mobile devices
Mobile device technologies have come a long way in terms of system or component integration and characterisation.
Mobile devices including smartphones, tablets, eReaders, laptops and netbooks are currently embedded with many devices such as sensors, accelerometers, gyroscope, speakers and others which have been reduced in size and weight.
Over the last 5 years, MEMS have been extensively deployed and introduced in mobile devices as well as other consumer electronics such as game consoles, digital camera, inkjet printers, projectors and pressure checks for various aspects and elements of their design including sensors, display, audio and RF components.
Prime examples of this kind of device sophistication and development are the iPhone and Nintendo Wii.
The iPhone, from a mobile device standpoint, is primarily responsible for spurring the demand for MEMS devices.
The gyroscope based on MEMS was featured in the iPhone 4 to detect the orientation by measuring vibrations detected by the electronic circuit.
Apple also uses MEMS accelerometers in the iPhone as well as in the iPod Touch and iPad to detect the speed and direction of the tilted side and orientate the screen accordingly.
Other smartphone devices including BlackBerry Torch also make use of MEMS accelerometers and gyroscopes.
