摘要/Abstract

摘要：

光学体积描记（PPG, photo plethysmo graphy）因其设计简单、成本低、信号周期能有效反应心脏节律等特点被广泛应用于检测心率及脉搏活动。基于多量子阱（MQW, multiple quantum well）二极管发光谱与探测谱存在重叠区的物理现象，采用兼容工艺在一块氮化镓芯片上实现光发射和接收器件的集成，研制收发一体式集成光电子芯片及脉搏传感器。实验结果表明，该氮化镓集成光电子芯片能够有效地接收经过心脏脉冲调制过的反射光。结合电路处理，能够根据还原的PPG信号计算出测试者的心率及脉搏跳变频率，以此起到检测和警示的作用。

关键词: 光学体积描记, 脉搏检测传感器, 单片氮化镓集成光电子芯片

Abstract:

Photo plethysmo graphy (PPG) is widely used to detect heart rate and pulse activity due to its simple design, low cost, and signal cycle that can effectively reflect the heart rhythm.Owing to the partial overlap between the emission and the detection spectra of GaN multiple quantum well (MQW) diode, the MQW receiver can respond to the light emitted from the transmitter sharing identical MQW structures.Thus, the fabricate and characterize monolithic integration of GaN transmitter and receiver was proposed as a single unit onto a conventional GaN-on-sapphire platform.This not only can effectively reduce the size and cost of the device, but also fully improves the sensitivity of the system.The experimental results show that the gallium nitride integrated optoelectronic chip can effectively receive the reflected light modulated by the heart pulse.Combined with circuit processing, the tester’s heart rate and pulse beat frequency can be calculated according to the restored PPG signal, so as to play the role of detection and warning.

Key words: photo plethysmo graphy, pulse detection sensor, monolithic integration of GaN optoelectronic chip
