Minimum Requirements for Feedback Enhanced Force Sensing [PDF]

open access: yesPhysical Review Letters, 2013
The problem of estimating an unknown force driving a linear oscillator is revisited. When using linear measurement, feedback is often cited as a mechanism to enhance bandwidth or sensitivity. We show that as long as the oscillator dynamics are known, there exists a real-time estimation strategy that reproduces the same measurement record as any ...

High-Force Magnetic Tweezers with Hysteresis-Free Force Feedback. [PDF]

open access: yesBiophys J, 2020
ABSTRACTMagnetic tweezers based on solenoids with iron alloy cores are widely used to apply large forces (~100 nN) onto micron-sized (~5 μm) superparamagnetic particles for mechanical manipulation or microrheological measurements at the cellular and molecular level.

Rotational force-feedback wrist [PDF]

open access: yesProceedings of the IEEE International Symposium onAssembly and Task Planning, 2003., 2004
Force-feedback structures are mechanical structures that can generate forces to restore to the user a tactile feeling corresponding to the world in which he is manipulating an object. This paper presents the mechanical design of a 3-rotational-degrees-of-freedom (DOF) wrist able to produce force feedback. The wrist, plugged on an existing 3-translation-

Force feedback pushing scheme for micromanipulation applications [PDF]

open access: yes, 2009
Pushing micro-objects using point contact provides more flexibility and less complexity compared to pick and place operation. Due to the fact that in micro-world surface forces are much more dominant than inertial forces and these forces are ...

Freeform Extrusion of High Solids Loading Ceramic Slurries, Part II: Extrusion Process Control [PDF]

open access: yes, 2006
Part I of this paper provided a detailed description of a novel fabrication machine for high solids loading ceramic slurry extrusion and presented an empirical model of the ceramic extrusion process, with ram velocity as the input and extrusion force ...

Comparing two haptic interfaces for multimodal graph rendering [PDF]

open access: yes, 2002
This paper describes the evaluation of two multimodal interfaces designed to provide visually impaired people with access to various types of graphs. The interfaces consist of audio and haptics which is rendered on commercially available force feedback ...

Semi-autonomous scheme for pushing micro-objects [PDF]

open access: yes, 2009
-In many microassembly applications, it is often desirable to position and orient polygonal micro-objects lying on a planar surface. Pushing micro-objects using point contact provides more flexibility and less complexity compared to pick and place ...

Suppressing nano-scale stick-slip motion by feedback [PDF]

open access: yes, 2012
When a micro cantilever with a nano-scale tip is manipulated on a substrate with atomic-scale roughness, the periodic lateral frictional force and stochastic fluctuations may induce stick-slip motion of the cantilever tip, which greatly decreases the ...

Interfacial force sensor with force-feedback control [PDF]

open access: yesInternational Technical Digest on Electron Devices, 2002
A novel interfacial force microscope capable of measuring the forces between two surfaces over the entire range of surface separations, up to contact, has been developed. The design is centered around a differential capacitance displacement sensor where the common capacitor plate is supported by torsion bars.

Haptic perception of virtual roughness [PDF]

open access: yes, 2001
The texture of a virtual surface can both increase the sense of realism of an object as well as convey information about object identity, type, location, function, and so on.
