Bioinstrumentation
本课程讲授生物医学测量与仪器的原理与设计方法，涵盖传感器原理、信号调理、放大电路、滤波、模数转换与数据采集系统。学生学习心电图、脑电图、血氧、血压等生理信号的采集与处理技术，掌握噪声抑制、共模抑制、安全隔离等关键设计要点。课程结合现代医疗监护设备与可穿戴传感系统案例，培养硬件电路与系统集成能力。
This course covers principles and design of biomedical measurement instrumentation, including sensors, signal conditioning, amplifiers, filtering, A/D conversion, and data acquisition. Students learn acquisition and processing of ECG, EEG, SpO2, and blood pressure signals, with emphasis on noise reduction, common-mode rejection, and safety isolation. Cases include modern monitoring devices and wearable sensors, building hardware and system integration skills.
学生以小组为单位设计并搭建一台便携式三导联心电采集装置，包含模拟前端放大滤波电路、STM32单片机数据采集、蓝牙传输与上位机波形显示，完成噪声测试并撰写设计文档与演示。
In teams, students design and build a portable three-lead ECG acquisition device, including an analog front-end amplifier and filter circuit, STM32 microcontroller data acquisition, Bluetooth transmission, and PC waveform display. They perform noise testing and submit design documentation and a demonstration.
