可穿戴产品


几乎所有传统的临床监测体征信号,现在都可以通过可穿戴产品进行采集,精度水平也非常接近。传统信号包括:

  • 脉搏/心率
  • 血氧
  • 应力
  • 心电图(EKG/ECG)
  • 体温
  • 紫外光(皮肤照射)



应用


电源和电池管理

可穿戴产品中,电源系统必须能够调节电池的输出电压——电池是电压输出逐渐下降的电压源。稳压器的效率必须足够高,以最大程度利用电量,也必须提供设计要求的供电电压。可充电Li+电池的可用电压范围为4.2V至大约3.2V。大多数可穿戴产品使用的主电源低于单节Li+电池的最低电压,所以主电源一般由降压型调节器提供。可穿戴产品中有些功能要求的电压可能高于单节电池提供的电压,所以电源管理功能必须包含至少一个升压调节器。所要求的供电电压数量取决于设备,但为了最大程度提高效率,最好将电源电压的通道数降至最少。

用于可穿戴产品的电源管理IC 

处理器

功耗和处理能力是选择微处理器的重要标准,需要采用系统划分策略确定哪些系统功能最好集成到微控制器内部,哪些功能可通过外部方式处理。由于可穿戴设备读取人体信号,所以必须综合考虑所有的片上模拟电路,以确保高精度处理弱小信号。

用于可穿戴产品的微控制器 

传感器及传感器接口

人体传感器输出信号的幅值非常低,为毫伏和微安级。用于可穿戴产品的集成电路将带放大功能的传感器与转换电路组合到单芯片或封装内。这些小尺寸、高精度方案能够提供较大幅值的模拟输出或串行数字输出。
