This article has been cited by other articles in PMC. Abstract A novel temperature sensor based on nematic liquid crystal permittivity as a sensing magnitude, is presented. This sensor consists of a specific micrometric structure that gives considerable advantages from other previous related liquid crystal LC sensors. The analytical study reveals that permittivity change with temperature is introduced in a hyperbolic cosine function, increasing the sensitivity term considerably. As it was predicted by the analytical study, the micrometric size of the proposed structure produces a high output voltage. Moreover the voltage's sensitivity to temperature response can be controlled by the applied voltage. This response allows temperature measurements to be carried out without any amplification or conditioning circuitry, with very low power consumption. Keywords: temperature sensors, liquid crystals, microstructure 1. Introduction Over time temperature monitoring has been an indispensable tool for sensing changes in many different processes and systems, in both research and industrial applications. Many diverse sectors, such as transport, control, automobile, industrial machinery, energy, medical, food, etc. Currently, the temperature sensors range is broad enough to categorize them according to different criteria; the main one is contact and non-contact sensors pyrometers. Nevertheless, the temperature dependent magnitude sensing magnitude and the inherent manufacturing technology are the rules mainly considered to classify them. In some way, this classification estimates the global extent of the conditioning and measurement circuits on the electrical design. The sensing magnitudes are usually connected to the output signals by a relationship derived from an interrogating circuit. Those signals often are in the electrical domain, such as a voltage, a current or a resistance; other times they are in the optical domain, for example, an optical transmittance or a reflectivity.

Introduction Over time temperature monitoring has been an indispensable tool for sensing changes in many different processes and systems, in both research and industrial applications.

Currently, the temperature sensors range is broad enough to categorize them according to different criteria; the main one is contact and non-contact sensors pyrometers. Nevertheless, the temperature dependent magnitude sensing magnitude and the inherent manufacturing technology are the rules mainly considered to classify them.

In some way, this classification estimates the global extent of the conditioning and measurement circuits on the electrical design. The sensing magnitudes are usually connected to the output signals by a relationship derived from an interrogating circuit.

Those signals often are in the electrical domain, such as a voltage, a current or a resistance; other times they are in the optical domain, for example, an optical transmittance or a reflectivity.

Conventional contact temperature sensors can be either metallic resistance temperature sensors, thermocouples, bimetallic structures or semiconductor thermistor, diode, chip integrated circuit -based transducers.

The highest sensitivities are typical of the semiconductor sensors with relative sensitivities ten times greater than those of metallic sensors [ 1 ]. In particular thermocouples exhibit a high linearity over a wide temperature range. In the last years one of the most used temperature sensors is the chip integrated circuit.

This sensor, based on integrated transistors, generates higher output than thermocouples, is more accurate than thermistors and is completely linear. As the circuitry is sealed it is not subject to oxidation.

The main disadvantages are the self-heating and the slow response. On the other hand, pyrometers use the radiation from very hot objects as a sensing magnitude through non-contact measurements.

An alternative technology for temperature sensing is the use of liquid crystals LCs. Ideally, the input current should be zero. I suspected maybe it was oscillating or pulling current in the off nominal case.
