摘要:
随着电子科技的发展，很多设备呈现出自动化的形式，自动化的电子设备可以给用户更加舒适的体感感受。精密测量人体皮肤电阻是使体感设备具备竞争力的一个先决条件。本文设计了一种用于测量皮肤电阻的仪器，通过将一个数字电压表头转换成数字电阻表头，将电阻数值显示出来，能够有效直观的读取被测电阻。通过选用ICL7107芯片实现测电阻功能，设计的皮肤电阻表体积小，测量精度高，在体感相关设备中具有广阔的应用前景。Under the development of electronic technology, many devices have been showing as automation system. The auto devices can take more comfortable feels for the users. It is a prerequisite for the body feelings devices to measure resistance of the body’s skin. The essay has designed an instru-ment to measure skin’s resistance by putting the digital voltmeter headers convert to digital re-sistance headers to show the numerical value of the resistance convenient to read effectively and intuitively. For the function comes true, we choose the chip ICL7107, because it is small in size and high precision in test and has the broad application prospect in the human feelings devices.
