加速度计在手机市场上迅速扩散，使得智能创新能够继续帮助开发者区分产品和竞争对手。
根据iSuppli，加速度计，迅速渗透手机市场，而且似乎在不久的将来不会。正如他们预测的，大约2010的移动电话中有三分之一是MEMS加速度计。这一比例从2008的五上升到2009的11。加速度计允许用户使用手指敲击和三维运动来执行特定命令，通常取代了多击键的需要。
例如，手机用户要求复杂的用户界面，允许快速、精确的通信，而不需要复杂的数据输入。他们还希望这些功能在预算价格的手机以及高端机型。飞思卡尔MMA7660FC低g，三轴数字加速度计是该公司的第一个是专为移动电话和其他小的手持设备。低成本，低功耗智能感应在一个紧凑的包可以添加巨大的功能，以便携式电池供电的设备，没有空余的余地。
Essentially， MEMS combine silicon-based microelectronics with micromachining technology. A three-axis accelerometer can detect motion on three different planes， or axes. This allows developers to implement a single accelerometer to incorporate tap， shake， and orientation detection in a mobile device. For instance， a back-and-forth shake and an up-and-down shake can be used to execute two different commands. Although accelerometers can be used in a number of hand-held applications， mobile phones have dominated the market. Accelerometers not only enable developers to incorporate clever innovations that differentiate their products from the competition， but also to extend revenue opportunities to ISVs （independent software vendors）， interface providers， and wireless service carriers.
The MMA7660FC accelerometer can be employed to detect natural user interactions， including：
Orientation detection that goes beyond automatically adjusting to a portrait or landscape configuration
Single-tap detection， which can be configured at user-selectable thresholds and time duration on the X， Y， and Z-axes
Shake， which can be used to represent specific keystrokes or a series of keystrokes
Gesturing and gaming moves， such as three-dimensional tilt， turn， and twist
However， portable devices such as mobile phones demand more than improved functionality alone if they want to carve out a profitable piece of the market. The inherent limitations of size and battery life， among others， must also be addressed.
