Product Description

Piezo-Resistive Sensing (PRS) probes are silicon cantilevers with an integrated piezo-resistor for self-sensing scanning probe microscopy applications. The piezo-resistors are integrated into a matched Wheatstone bridge to optimize the sensitivity and compensate environmental thermal drift. By using the self-sensing readout no laser adjustment is necessary in comparison to conventional optical readout AFM systems. This gains time during a cantilever change. Furthermore free space above the cantilever opens a door for new applications and various instrument combinations.

The cantilever provides a sharp tip for accurate measurements in various applications. The cantilever chip is bonded onto a small printed circuit board with a small connector. The loading process of a fragile cantilever equipped with a connector is more easy and save. The counterpart PCB of the cantilever PCB is connected to a low-noise pre-amplifier by a flat-flex-cable.

Applications

  • Integration on a standard AFM scanner
  • Force or deflection measurement within TEM, SEM, XPS, etc.
  • Torque magnetometry
  • Tip-scanning high-speed AFM
  • Various cantilever based sensor applications (media properties, air pressure/acoustic wave, etc.)
