Friction and damping of a compliant foot based on granular jamming for legged robots

Auke Ijspeert, Simon Lukas Hauser, Peter Eckert, Alexandre Tuleu

Moving away from simple foot designs of current quadruped robots towards a more bio-inspired approach, a novel foot design was implemented on the quadruped robot Oncilla. These feet mimic soft paw-pads of dogs and cats with high traction and soft underlyin ...

Relevance of the Drag Force during Controlled Translocation of a DNA–Protein Complex through a Glass Nanocapillary

Aleksandra Radenovic, Sanjin Marion, Roman Bulushev

Combination of glass nanocapillaries with optical tweezers allowed us to detect DNA-protein complexes in physiological conditions. In this system, a protein bound to DNA is characterized by a simultaneous change of the force and ionic current signals from ...

Smart Knee Prosthesis for Orthopedic Surgery: the implantable and wearable Measurement System

Kamiar Aminian, Philippe Renaud, Arash Arami, David Forchelet

Recent advances in remote powering and telemetry permitted the use of sensors inside body. A few studies have been already done on smart knee prostheses, but all focused on monitoring the in-vivo contact forces and moments. A smart design, compatible with ...

MOVING ALONG In biomechanics, rehabilitation engineering, and movement analysis, Italian researchers are making great strides

Silvestro Micera

In Italy, biomechanics research and the analysis of human and animal movement have had a very long history, beginning with the exceptional pioneering work of Leonardo da Vinci. In 1489, da Vinci began investigating human anatomy, including an examination o ...

Wear at the asperity level: An atomistic viewpoint

Jean-François Molinari, Ramin Aghababaei, Derek Warner

Tribological problems are particularly difficult to comprehend. Different physical mechanisms (including the environment, plastic deformation, third body interactions, phase transformations, recrystallization) interact at disparate length and time scales. ...

Property changes in thermo-hydro-mechanical processing COST Action FP0904 2010-2014: Thermo-hydro-mechanical wood behavior and processing

Parviz Navi

Thermo-hydro-mechanical (THM) treatment is a combined action of temperature, moisture, and mechanical force, which leads to modified wood (THMW). Various types of eco-friendly THM processes have been developed to enhance wood properties and generate new ma ...

Force and Work Measurements: The Beginnings

Jean-François Loude

The first practical, portable “dynamometer”, designed in 1798 by Regnier, was used to quantify the muscular strength of men and animals. It was promptly used by ethnologists to test the strength of the “savages”. A smaller improved model (Collin dynamomete ...

Early Dynamometers (from Muscle to Steam Power)

Jean-François Loude

Spring balances, based on Hooke’s law, have been used for weighing since the early 18th century. At the end of the century, naturalists such as Buffon felt the need to quantify the muscular force of men (humans) and animals. The first practical, portable “ ...

Thick-film Load-sensing bridges – Effect of Temperature and Mechanical Boundary Conditions

Peter Ryser, Thomas Maeder, Caroline Jacq

Although inorganic thick-film materials are usually very stable, load sensors (i.e. force, torque and pressure) based on the piezoresistive effect of thick-film resistors often exhibit some drift, with major contributions stemming from a) temperature chang ...

Empirical Modeling of a Squeeze Film Haptic Actuator

Yves Perriard, Miroslav Markovic, Christophe Winter

In the analysis of squeeze film haptic tactile feedback actuators, attention is focused on establishing an empirical model of the force generated on the user's finger. The model is based on finite-element simulations which take into account the real motion ...
