Embroidered Textile Capacitive Sensor for Sucrose Solutions Measurement
2020
With the trend of textile sensors, embroidered sensors for body fluids measurements are getting attention. In this paper, an embroidered textile sensor with a capacitive spiral structure is proposed and used to measure the capacitance when being poured by sucrose solutions with different levels of concentration at different frequencies. Since the coefficient of determination $(\mathrm{R}^{2})$ near 0.997 from 250 Hz to 500 Hz shows the curves fitting well, the feasibility of the capacitance varying with different levels of concentration (0 - 250 mg/dl) in a linear curve at certain frequency range (250 - 500 Hz) is confirmed.
