Flexible robotics and smart wearable technologies are under intensive research due to their potential applications. Flexible sensors that are an essential part of these systems are mainly made of a soft polymer matrix and an electric conductive reinforcement. However, when a flexible sensor is heated or an electric current is applied a joule heating effect is produced rising the material´s temperature, and since soft polymers are temperature-sensitive there is a change in their physical dimensions, giving as a result, a dramatic change in their electric properties. This work contributes to a better understanding of the temperature´s effect on the piezoresistive properties of these sensors, (i.e.) the electric resistance of some sensors changed from ohms at room temperature to Mega-ohms at 80 °C, these change were possible due to an excellent thermal conductivity and heat distribution of the flexible resultant composites, as well as, the physical expansion of the polymer matrix reducing the milled carbon fibers´ interconnectivity and increasing the potential barrier between them.

柔性机器人技术和智能可穿戴技术由于其潜在的应用而正在深入研究。作为这些系统必不可少的一部分的柔性传感器主要由柔软的聚合物基体和导电增强材料制成。但是，当加热柔性传感器或施加电流时，会产生焦耳热效应，从而升高材料的温度，并且由于软聚合物对温度敏感，因此它们的物理尺寸会发生变化，结果是，其电性能发生巨大变化。这项工作有助于更好地了解温度对这些传感器的压阻特性的影响，例如，某些传感器的电阻从室温下的欧姆变为80°C下的兆欧姆，
