Sánchez-Pena, "Liquid Crystal Temperature Sensor Based on Three Electrodes and a High-Resistivity Layer," in IEEE Sensors Journal, vol. 15, no. 9, pp. 5222-5227, Sept. 2015, doi: 10.1109/JSEN.2015.2439334.1530-437Xhttps://hdl.handle.net/10115/29057— In this paper, a novel liquid crystal (LC) temperature sensor is proposed and theoretically analyzed. A detailed analytical model has been presented. The sensor is designed and optimized to produce maximum sensitivities. This sensor is composed of only three electrodes. The electrodes are very simple and can be easily designed for different sizes. The structure uses the temperature dependence of the LC permittivity as sensing magnitude. Several LC have been investigated. The response improves the characteristics of previous LC sensors and even some commercial sensors in terms of sensitivity or linearity. The sensor has a high sensitivity, low-voltage control, low power consumption, and high linearity. The main advantage is the possible integration of this sensor in other LC devices.engTemperature sensorsthin filmliquid crystalsinfo:eu-repo/semantics/article10.1109/JSEN.2015.2439334info:eu-repo/semantics/restrictedAccess
