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 ...

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 ...

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 ...

Learning Force and Position Constraints in Human-robot Cooperative Transportation

Sylvain Calinon

Physical interaction between humans and robots arises a large set of challenging problems involving hardware, safety, control and cognitive aspects, among others. In this context, the cooperative (two or more people/robots) transportation of bulky loads in ...

Towards displacement-based seismic design of modern unreinforced masonry structures

Katrin Beyer, Sarah Petry, Alessandro Paparo, Marco Tondelli

Unreinforced masonry (URM) structures are known to be rather vulnerable to seismic loading. Modern URM buildings with reinforced concrete (RC) slabs might, however, have an acceptable seismic performance for regions of low to moderate seismicity. In partic ...

Optical force sensing element and microsurgical instrument

Simon Nessim Henein

The present invention related to an optical force sensing element for microsurgical instruments (22), for measuring force F in three orthogonal directions x, y, z, comprising a monolithic cylinder structure (1), a cylindrical surface (4) and a top surface ...

Interaction of a point charge with the surface of a uniaxial dielectric

Primoz Rebernik Ribic

We analyze the force on a point charge moving at relativistic speeds parallel to the surface of a uniaxial dielectric. Two cases are examined: a lossless dielectric with no dispersion and a dielectric with a plasma-type response. The treatment focuses on t ...

Dependence of the most probable and average bond rupture force on the force loading rate: First order correction to the Bell-Evans model

Giovanni Dietler, Fabrizio Benedetti

The Bell-Evans model which predicts the linear dependence of the most probable intermolecular bond rupture force on the logarithm of stretching force loading rate is usually used to discuss the dynamic force spectroscopy experiment data. This model is cons ...
