Abstract
A capacitive-type humidity sensor has been manufactured using crosslin ked poly(methyl methacrylate-co-(2 hydroxypropyl)-methacrylate) as sen sing material. The sensitivity, response time and durability of the se nsor against acetone vapour have been measured. The sensor is tested w ith a measurement cycle as follows: 12% RH (1 h)-75% RH (1 h)-95% RH ( 16 h)-75% RH (I h)-12% RH (1 h), and it shows good sensitivity, short response time, low hysteresis and durability against acetone vapour.
