　　多传感器设备加速设计，简化供应链，切割成本

　　毫无疑问，下一代智能手机的设计者将在他们的材料清单中添加陀螺仪，以增强游戏功能和室内基于位置的服务。

　　一些供应商，如半导体，是使它更容易为设计者利用模数转换器通道在加速度计陀螺仪和其他容易同伴芯片集成。

　　但是，最有可能的是，我们将开始看到，除了多轴陀螺仪，更多的多传感器包结合加速度计和陀螺仪。

　　驱动这些多传感器设备的需求，特别是对移动电话和游戏平台的需求，将是简化设计和简化供应链的需要。虽然许多数字罗盘已经纳入GPS手机的加速度计，陀螺仪（又名常规速率或偏航传感器）和加速度计刚刚开始集成在同一模块中。

　　Like any other integrated device， an important step in their widespread adoption will be competitive pricing compared to discrete solutions.

　　While the key motivations for high integration are saving space and simplifying the design work for signal processing， integration also has to be cheaper than discrete solutions， said Jérémie Bouchaud， director and principal analyst MEMS， iSuppli Corporation.

　　According to Bouchaud， multisensor packages cost about 10 to 15 percent less than the costs of individual sensors.

　　The compass for a GPS phone always needs an accelerometer for calibration， which is why it makes sense to integrate it in the same package， said Bouchaud. The same thing will happen with gyroscopes， particularly for cell phone and gaming applications， he said.
