Karumbaiah N. Chappanda, et al., "Trianglamine Hydrochloride Crystals for a Highly Sensitive and Selective Humidity Sensor", Sensors and Actuators B: Chemical 294, 2019, 40. In this work, we present a highly sensitive and selective capacitive humidity sensor. Trianglamine hydrochloride is used as the sensing material, which is synthesized by a cyclocondensation reaction between terpthaldehyde and 1R,2R-cyclohexanediamine followed by addition of hydrochloric acid and vapor diffusion of acetone. The crystalline trianglamine hydrochloride salts are dispersed in acetonitrile and then coated
