穿戴式儿童情感识别系统中心电信号放大器的设计

Design for the ECG Signal Collection Component in the Wearable System for Child-Emotion Recognition

研究表明儿童时期具有的情绪能力,是他们以后生活中能否成功的最好预示。虽然情绪是一种主观意识,但情绪状态的变化总会伴随一定的生理变化。从而我们可以从生理参数的角度,用一套客观的评价标准来研究情绪状态。为了让测试儿童处在一个相对自然的状态,使情绪识别结果的可信度更高,我们提出了"穿戴式"生理参数采集系统的概念。本文的研究重点就是实现这个系统中的心电信号采集部分。

Recent researches show that children＇s emotion ability can indicate their future achievement.Emotions are typically associated with observable physiological changing patterns as well as subjective appraisals and cognitive components representation.In order to prevent the devices from influencing the children＇s nature state,we proposed the concept of ＂Wearable＂ system.The emphasis of this paper is to realize the collecting part of ECG signal in this system.
