The phenomenon
Inside Dragonfly®
Deform a piezoelectric crystal.
Shown: IEPE Dragonfly®
What it reveals
From tension to friction, one sensor reads it all.
Tension & compression
The structure stretches and shortens, and Dragonfly® reads the axial strain in real time.
Measured directly
Measured directly: dynamic surface strain. Load, torque and friction are derived from it through application-specific calibration.
Performance
Measured side by side with the sensors it replaces.

Dynamic surface strain: the tiny deformations a structure goes through when it vibrates, bends, twists or takes a shock. Load, torque and friction can be derived from it through application-specific calibration.
It measures strain directly, like a strain gauge, and follows fast dynamic events, like an accelerometer. The Passive version reaches below 0.01 Hz, the IEPE version beyond 100 kHz, with a noise floor around 1000 times lower than a bonded strain gauge.
It is bonded to the surface with a standard structural adhesive: cyanoacrylate for quick lab tests, epoxy for permanent installations. No drilling and no screws, and the flex follows curved surfaces down to a 2 cm bend radius.
The IEPE version plugs into any IEPE / ICP® compatible input. The Passive version works with a charge amplifier, and the IO version connects through a shielded M12 connector. If you have no acquisition chain yet, we supply the whole one: acquisition, dashboard and engineering.
The Passive version operates from −55 °C to +140 °C, the IEPE and IO versions from −55 °C to +125 °C. All three tolerate short exposures up to 150 °C, for 4 hours.
