Excitation Source Design for Impedance Measurement of Human Skin
摘要
Abstract
During the skin impedance measurement, the high quality of excitation source is critical to the measurement system. This paper designs a current mode excitation source based on the AD9851 and STC89C52 ,whose current amplitude and frequency can be adjusted in a certain range.It can be used in skin impedance measurement. Experiments show that the signal source has stable output signal amplitude and frequency, and high output impedance.关键词
