Analog Devices showed off their carbon nanotube sensors at Sensor+Test 2023, with an expected release of the product later in the year. This board form serves as an initial point of enquiry for those looking to be an early adopter of this technology. The key points regarding this innovation, based on interviews and research conducted by ipXchange, are summarised as follows:
-> The sensor is based on a resistive network of carbon nanotubes within a polymer substrate.
-> This sensor can be integrated into a structure to monitor the propagation of cracks, which create a permanent change in the resistance of the sensor by breaking a portion of the carbon nanotubes.
-> This sensor can detect cracks at a resolution of 0.02 mm with an accuracy of 90%.
-> The sensor is passive and only requires power in order to read the resistance.
-> This solution is suitable for monitoring applications in buildings, bridges, railways, mining, etc.
Analog Devices currently pairs test versions of this technology with a data acquisition module that features wireless connectivity, though no official evaluation kit has been revealed at this time.
