Researchers turn up the heat on flexible temperature sensor development

Engineers from UK universities have developed a new method of measuring temperature through the interaction of a soft and flexible 'smart skin' sensor with electromagnetic waves. Engineers from UK universities have developed a new method of measuring temperature through the interaction of a soft and flexible 'smart skin' sensor with electromagnetic waves. The sensor developed by the team is made from a composite of carbon fibres and silicon rubber, and works without battery power or onboard processing. https://youtu.be/ymFSxZh4JmQ The flexible sensor's ability to absorb and reflect radio-frequency (RF) signals varies with atmospheric heat or cold, enabling the sensing of temperature across a much greater range than other comparable devices. It can also withstand thousands of cycles of bending and stretching without losing its sensitivity to temperature. Temperature sensors are found in almost all electronic devices, and the global market for the technology is currently valued between $5-8bn. Typical temperature sensors, known as thermistors, work by changing resistance in response to changes in temperature.
