We present a new microfluidic device and method based on cantilever sensing technology. Utilizing an artificially created force gradient the method can be applied for the non-destructive calibration of the normal spring constant of micro-cantilevers. In contrast to the most recent efforts to advance cantilever calibration, our method can be performed in situ, is easy to use, reliable, accurate, and non-destructive, i.e., does not involve any contact between the cantilever and another surface. The method has great potential for the calibration of modified probes, bio-sensor cantilevers etc. In addition, provided the dynamic properties of the cantilever sensor are designed and clearly defined, the device can be easily incorporated in microfluidic systems to measure the velocity of fluid flows.
