Piezoresistive Cantilever Optimization and Applications
Piezoresistors are commonly used in microsystems for transducing force, displacement, pressure and acceleration. Silicon piezoresistors can be fabricated using ion implantation, diffusion or epitaxy and are widely used for their low cost and electronic readout. However, the design of piezoresistive cantilevers is complicated by coupling between design parameters as well as fabrication and appli...
متن کاملPiezoresistive cantilever force-clamp system.
We present a microelectromechanical device-based tool, namely, a force-clamp system that sets or "clamps" the scaled force and can apply designed loading profiles (e.g., constant, sinusoidal) of a desired magnitude. The system implements a piezoresistive cantilever as a force sensor and the built-in capacitive sensor of a piezoelectric actuator as a displacement sensor, such that sample indenta...
متن کاملPiezoresistive cantilever designed for torque magnetometry
New piezoresistive silicon cantilevers designed specifically for torque magnetometry on microscopic samples have been microfabricated and tested. These levers have been optimized to detect the torque in two directions corresponding to flexion and torsion. Torque resolution of ;10 N m can be achieved depending on the operating mode. In one version an integrated loop allows an absolute calibratio...
متن کاملPiezoresistive cantilever array for life sciences applications
Atomic Force Microscopy (AFM) techniques are used with oneor two-dimensional arrays of piezoresistive probes for parallel imaging. We present a newly designed AFM platform to drive these passivated piezoresistive cantilever arrays in air and liquid environments. Large area imaging in liquid as well as qualitative and quantitative analysis of biological cells are demonstrated by the means of pie...
متن کاملDesign and Simulation of Piezoelectric MEMS Cantilever
In this paper, a Micro – Electrical Mechanical System (MEMS) energy harvester is developed, using the phenomenon of Piezoelectricity. Zinc Oxide (ZnO) was chosen as the piezoelectric material. A multi – d31 mode cantilever design was used with varying dimensions of cantilever, to form an array. The individual cantilevers can be either connected in series or parallel to achieve different output ...
