FT-S Microforce Sensing Probe

FT-S Microforce Sensing Probes

The newest generation of FemtoTools FT-S Microforce Sensing Probes are microforce sensors capable of measuring forces from 200 millinewtons (0.2 N) down to sub-nanonewtons (10-9 N) along the sensor’s probe axis. Both compression and tension forces can be measured. The outstanding long-term stability and low signal drift guarantees significantly higher measurement accuracy than any other force sensing system in this force range. The accuracy of the FemtoTools SI-traceable calibration process is ensured by comaparitive measurements with the Swiss National Institute of Metrology (METAS).

FT-G Force Sensing Microgripper

FT-G Force Sensing Microgripper

The FT-G Microgripper series is designed to handle objects ranging from 0.001 mm to 0.1 mm. The initial openings of the gripper arms are 30 μm and 100 μm. Typical applications include sample preparation and microassembly tasks (pick-and-place).

The gripper opening can be controlled with nanometer precision, such that the gripper arms are fully closed upon applying the maximum actuation signal. Due to the electrostatic actuation principle, the gripper arms do not heat up.

The FT-G103 and the FT-G33 feature an integrated force sensor for closed-loop control of the gripping force (unique on the market). This enables the handling of fragile samples, the detection of (un)successful gripping, the detection of objects size and the measurement of the mechanical properties of the sample to be picked-up.
