Contact force analysis of deformable finger

International Journal of Computational Vision and Robotics, 2010
For robots, gripper designs constitute an important problem. It involves the design of actuation mechanism, gripper fingers and robot-grippers interface. Considering the gripper fingers, it can be hard or a soft one. The soft fingered grippers can handle the objects very efficiently and without causing damage to the object surface.

The effect of contacting force on photoplethysmographic signals

Physiological Measurement, 2004
Photoplethysmography (PPG) has been used in oxygen saturation measurement, heart rate monitoring, and the assessment of peripheral circulation and large artery compliance. However, the waveform of the photoplethysmographic signal may be affected by the contacting force between the sensor and the measurement site. The aim of this study is to investigate

Contact Tasks Realization by Sensing Contact Forces

1997
A key issue in robotized realization of any type of the contact task is the control of forces arising during contact between the object and the environment. The most common way of force measurement is with a force sensor, usually placed at the robot wrist, which can measure all six components of force and moment.

Contact electrification using force microscopy

Physical Review Letters, 1989
One of the oldest unresolved problems in physics is the mechanism of charge exchange between contacting surfaces when at least one of them is insulating. We describe a new technique, using force microscopy, for studying this problem with greater lateral resolution than has been previously possible. The force microscope is shown to have 0.2 \ensuremath{\

Contact Force Models for Multibody Dynamics

2016
In this book, several compliant contact force models are analyzed within the context of multibody dynamics, in which the main issues associated with the fundamental contact mechanics are also revisited. In particular, various contact force models from linear to nonlinear, purely elastic to dissipative contact force models are presented and their ...

Pure Elastic Contact Force Models

2016
The most important pure elastic constitutive laws commonly utilized to model and analyze contact-impact events in the context of multibody mechanical system dynamics are presented in this chapter. Additionally, the fundamental issues related to the generalized contact kinematics, developed under the framework of multibody system dynamics formulation ...

Contact Force and Friction

2013
This chapter introduces contact forces and pressures and its modelling; consequent to this is friction as occurs within the structure and between the constituent components. Various friction or more correctly energy dissipative mechanisms are identified and are grouped into two categories; those that arise because of relative motion between components ...

‘May the contact lens force be with you’

Contact Lens and Anterior Eye, 2016
FULL TEXT: Like many people one of my favourite pastimes over the holiday season is to watch the great movies that are offered on the television channels and new releases in the movie theatres or catching up on those DVDs that you have been wanting to watch all year.
