Hearing: Its Physiology and Pathophysiology
Thus in an electrical circuit, electrical current corresponds to vibration velocity
and electrical voltage corresponds to mechanical force. The mechanical
impedance, Z, is therefore the ratio between force, F, and velocity, V. Mechanical
friction ...

Ethics and Mental Health: The Patient, Profession and Community
The amount of force that is required to produce a given vibration response is
known as the mechanical impedance. More specifically, mechanical impedance
is defined as the ratio of the peak oscillatory force exerted on an object by a
vibration ...

A New Actuation Approach for Bio-inspired Human-friendly Robots
Mechanical impedance is a measure of how much a mechanical system resists
motion given a force. The basic equation of mechanical impedance is Z = F ext (s
) τext(s) ̇x(s) ̇ θ(s) or Z= (2.3) where Fext (τext) and ̇x ( ̇θ) are force (torque)
...

Impedance Adaptation Methods of the Piezoelectric Energy ...
3.4 Mechanical Impedance of the System Mechanical impedance (Zm) is defined
as the ratio of the driving force to the velocity of the system at the point where the
force is applied. The dimensions of mechanical impedance are the same as ...
