Abstract

本申请实施例公开了一种PPG传感器，该PPG包括第一PD、第一LED和第二LED，其中，第一PD与第一LED之间的距离与第一PD与第二LED之间的距离不等。如此，在该PPG传感器中，可以形成两个大小不同的PD与LED之间的距离。该两个不同PD与LED之间距离可以满足不同应用场景下对PD与LED之间距离的要求，具体地，该PPG传感器能够兼顾静态心率测量、动态心率测量、佩戴松紧检测和血氧测量等四种应用需求。基于此，本申请实施例还提供了一种包括该PPG传感器的智能手表或手环。

An embodiment of the present application discloses a PPG sensor. The PPG includes a first PD, a first LED and a second LED, wherein the distance between the first PD and the first LED is the same as the distance between the first PD and the second LED. Distances vary. In this way, in the PPG sensor, the distance between two PDs and LEDs with different sizes can be formed. The distance between the two different PDs and the LED can meet the requirements for the distance between the PD and the LED in different application scenarios. Specifically, the PPG sensor can take into account static heart rate measurement, dynamic heart rate measurement, wearing tightness detection and blood oxygen measurement, etc. Four application requirements. Based on this, the embodiments of the present application also provide a smart watch or bracelet including the PPG sensor.
