摘要

这个现场演示展示了一个便携式肠道声音识别系统。该系统由一个电荷放大器和一个压电传感器组成。一个识别单元，由峰谷检测器，微分器，积分器和比较器组成，结合起来积极识别肠道声音。该系统的识别率为85%，功耗为53 μW，实现面积为0.96 mm2。所设计的系统适合与其他传感系统集成。

Live Demonstration: Portable Bowel Sound Idenfication System

This live demonstration showcases a portable bowel sound identification system. The system consists of a charge amplifier interfaced with a piezoelectric sensor. An identification unit, consisting of peak and trough detectors, differentiators, integrators and comparators, combine to positively identify bowel sounds. The system has an 85% identification rate, uses 53 μW of power, and is implemented in a 0.96 mm2 area. The designed system is suitable for integration with other sensing systems.
