A silicone rubber surface RTD sensor is a rectangular, flat, flexible, silicone rubber-laminated sensor that monitors or measures temperature on round or uneven surfaces.
The silicone rubber surface RTD sensors are frequently utilized in the windings' final turns for motor and generator applications. An optical fiber-based soft curvature sensor is proposed to meet the needs for measuring curvature in biomedical intelligent equipment, soft robots, and the intricate structures of major infrastructures.
Obtaining a soft curvature sensor with extraordinary high sensitivity and repeatability is the main contribution. The polyvinyl chloride (PVC) reinforced silicone rubber substrate is made by adhering a silicone rubber sheet to the surface of polyvinyl chloride. The sensor is made by embedding the fiber Bragg grating into the substrate. Standard curvature calibration blocks are used to calibrate the sensor.
The sensor's reflected spectrum characteristic is examined. It is possible to establish a connection between the sensitivity and the fiber embedded depth. The research demonstrates that the sensor is capable of taking real-time measurements of structure curvature.
The sensor's sensitivity and repeatability can both be improved with the help of the silicone rubber substrate that is reinforced with polyvinyl chloride. The maximum level of sensitivity is 329.2 pm/m1. The sensor can be used to measure the curvature of flexible mechanisms and complex structures because it has good consistency over multiple measurements.
The Global Silicone Rubber sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Durex offers surface mount silicone resistance temperature detectors that can be directly mounted to flat or curved surfaces and utilize the same technology as a sealed silicone rubber heater. The design of the silicone rubber RTD temperature sensor can be made to order in a variety of thicknesses and comes with an adhesive backing for easy application.
Wrapping the RTD sensor around curved surfaces like cooling or water lines can be accomplished with a thinner profile. The other is contacting measurement, in which sensors are embedded in or attached to the surface of measured objects.
The first method, which was mostly used to measure the structure's curvature and three-dimensional shape, can achieve high measuring accuracy, but it has two issues: First, special equipment cannot be placed around the measured moving objects with non-contact measurement due to its limited operating range and portability.
It is challenging to meet the measurement requirements of practical operation, such as sensing soft robots, intelligent wearable devices, and so on. Second, measuring the curvature and shape of some closed surfaces or intricate structures can be challenging.
