WIRELESS TORQUE SENSING

Usually, torque is measured indirectly through the current in electric drives. However, in applications with gearboxes or clutches, this data is of limited significance. In contrast, our method provides real-time torque data measured directly on the shaft and is applicable to all types of drives.

Instead of strain gauges with complicated read-out systems, we apply metamaterial discs to the shaft, enabling precise, real-time measurements with off-the-shelf, low-cost radar sensors. This innovative approach unlocks a wide range of new possibilities and outstanding benefits.
