SILICON LABS Si1172人体生物测量传感器将PPG及ECG测量集成在一起，可对人体PPG及ECG信号同时测量，可以测量人体的心率及心电生物信号，还可以进一步去判断人体的疲劳度及健康状况，广泛应用于可穿戴产品智能手环手表。

Si1172具有超低功耗，高信噪比及低噪声ECG接口等优势性能。Si1172 心电传感器在执行连续的生物信号测量消耗的功耗低于50 μA（包含传感器和LED），内置的缓冲区和加速计同步功能可以节省更多的系统级耗电。高信噪比SNR＞100dB，以及消除环境噪声和错误数据的能力，产生了高质量的信号，尽管具有挑战性的生理特征、不同的肤色和纹身的存在，它更容易追踪心率。低噪声ECG接口（支持导联开关检测）允许您独立于PPG测量或与PPG测量交织地进行ECG测量。

下图是Si1172传感器的内部结构框图，可驱动4路LED，电流1.7mA-310mA可调，内部集成高效率LED，大面积PD接收，高精度24位ADC、内部集成2kB 缓存、I2C和SPI数字接口、可编程事件中断接口。

Silicon Labs Si1172人体生物识别传感器给可穿戴设备中的心率监测增添更高级的心电图ECG测量功能，从而获得更有价值的生理参数，使智能穿戴设备更智能。

用Si1144来实现心率测试功能，测试的原理是什么？

Si114x利用LED发出的绿光和红外光，以及两种光传感器来检测心率。当其处于15摄氏度（59华氏度）以下的低温时，通过测量绿光的吸收状况来获取更为精准的数据。而高温环境下，比如用户正在健身房里挥汗如雨时，皮肤表面水分增加，由于更多绿光已经被吸收掉，要检测皮下反射的绿光就比较困难。这种用于血流检测的光学技术，专业上称为“光电容积脉搏波描记法（photoplethysmography）”，简称PPG。绿光PPG和EKG（心电图）获取的数据更接近。“光电容积脉搏波描记法（photoplethysmography）”的英文单词读起来难，但原理却很简单：血液是红色的，所以反射红光，吸收绿光。Si114x结合绿色LED光及感光光电二极管，可以检测出特定时间手腕处流通的血液量。具体过程如：心脏跳动的一瞬间，手腕处流通的血液量增加，会吸收更多绿光；而心跳间隙，吸收的绿光就少一些。Si114x上的LED光每秒闪动数百次，计算出每分钟的心跳次数，也就得出心率值了。
