Optimal Excitation Force Design Indentation-Based Rapid Broadband Nanomechanical Spectroscopy

View page
US Patent:
8590061, Nov 19, 2013
Filed:
Mar 21, 2012
Appl. No.:
13/425456
Inventors:
Qingze Zou - Franklin Park NJ, US
Zhonghua Xu - Evanston IL, US
Assignee:
Iowa State University Research Foundation, Inc. - Ames IA
International Classification:
G01Q 10/06
US Classification:
850 4, 850 1, 850 5, 850 8, 850 10, 850 19
Abstract:
An optimal input design method and apparatus to achieve rapid broadband nanomechanical measurements of soft materials using the indentation-based method for the investigation of fast evolving phenomenon, such as the crystallization process of polymers, the nanomechanical measurement of live cell during cell movement, and force volume mapping of nonhomogeneous materials, are presented. The indentation-based nanomechanical measurement provides unique quantification of material properties at specified locations. Particularly, an input force profile with discrete spectrum is optimized to maximize the Fisher information matrix of the linear compliance model of the soft material.

US Patent:
20040233570, Nov 25, 2004
Filed:
Nov 21, 2003
Appl. No.:
10/718862
Inventors:
Santosh Devasia - Seattle WA, US
Qingze Zou - Seattle WA, US
Dhanakorn Iamratanakul - Seattle WA, US
Hector Rodriguez - Bucaramaanga, CO
Assignee:
University of Washington - Seattle WA
International Classification:
G11B005/596
US Classification:
360/078090
Abstract:
A method useful to change a system's output from one value to another within a prescribed time-interval in an optimal manner using optimization criteria such as minimal time (e.g., to increase throughput) or minimal energy (e.g., to reduce heat dissipation and reduce induced vibrations). Optimal design of maneuvers (such as fast seek and scanning) that rapidly change the output from one value to another, arise in flexible structure applications, including rapidly positioning the end-point of large-scale space manipulators, positioning of read/write heads of disk-drive servo systems, which are relatively medium-scale flexible structures, and nano-scale positioning and manipulation using relatively small-scale piezo actuators. Maintaining a position of an element constant outside of the transition time-interval is critical in many applications. For example, in disk-drive applications, read and write operations cannot be performed (before and after the output transition) if the output position is not precisely maintained at a desired track.

Method And Apparatus For Nanomechanical Measurement Using An Atomic Force Microscope

View page
US Patent:
20130347147, Dec 26, 2013
Filed:
Jun 24, 2013
Appl. No.:
13/925441
Inventors:
Qingze Zou - Bridgewater NJ, US
Juan Ren - Highland Park NJ, US
International Classification:
G01Q 60/38
US Classification:
850 40
Abstract:
A control-based approach is provided for achieving accurate indentation quantification in broadband and in-liquid nanomechanical property measurements using atomic force microscope (AFM). Accurate indentation measurement is desirable for probe-based material property characterization because the force applied and the indentation generated are the fundamental physical variables that are measured in the characterization process. Large measurement errors, however, occur when the measurement frequency range becomes large (i.e., broadband), or the indentation is measured in liquid on soft materials. Such large measurement errors are generated due to the inability of the conventional method to account for the convolution of the instrument dynamics with the viscoelastic response of the soft sample when the measurement frequency becomes large, and the random-like thermal drift and the distributive hydrodynamic force effects when measuring the indentation in liquid.
