Do you believe new sensor technology will significantly improve safety in dangerous industrial and rescue environments?
Scientists have developed a new flexible polyacrylonitrile fiber mat sensor capable of simultaneous temperature and pressure monitoring. The device maintains high performance even under significant mechanical stress and extreme heat.
Why it matters
Most existing flexible sensors struggle to survive high-temperature environments or degrade quickly under repeated mechanical use. This new material provides a robust solution for demanding industrial and safety applications.
The sensor operates across a pressure range of 0 to 480 kPa and temperatures from 25 °C to 300 °C. The fabricated 8x8 array, measuring 90x90 mm, achieves a response time of 53.2 ms at room temperature.
