Advances in Torque Sensor Technology That Are Likely to Shape the Future Potential of the Industry
1. Surface Acoustic Wave (SAW) Technology: Piezoelectric Surface Acoustic Sensing
The SAW technology utilizes piezoelectric substrates to generate acoustic waves. The propagation of these acoustic waves depends upon the applied torque. These sensors operate without batteries and are powered solely by an external interrogator's RF signal, that excites the SAW device, achieving accuracies better than 1% over wide temperature ranges. Notably, Transense Technologies’s AWsense platform integrates SAW resonator, which can measure torque with high accuracy (up to 0.1% full scale), enables reliable performance in harsh automotive and industrial environments.
2. Optical Technology: Fiber Optic Torque Sensing
Optical torque sensors typically measure torque by monitoring changes in light polarization, intensity or phase shift caused by the twisting of an optical fiber or grating embedded in the shaft. These sensors are able to detect minute angular displacements through changes in light wavelength or intensity, achieving sub-micrometer resolutions and bandwidths up to 10 kHz. Notably, Sensor Technology offer optical rotary torque transducers through ORT 230 / 240 series; these devices offer enhanced electronics for superior resolution (up to 50kHz bandwidth), and measurements from 10mNm to 100Nm.
3. Miniaturized Torque Sensor Technology: MEMS-Enabled Compact Torques
The miniaturization of torque sensors represents a pivot advancement in torque sensor technology, enabling seamless integration into compact devices and systems once limited by size constraints. These torque sensors leverage micro-electro-mechanical systems (MEMS) and are able to achieve dimensions under 10 mm and are able to integrate into humanoid robots, wearable exoskeletons and micro-drives, where space and weight are paramount. In September 2025, XJCSENSOR launched Next-Gen MEMS force torque sensor at World Robot Conference, held in Beijing, China.
