Microtubules as mechanical force sensors
Biosystems, 2007Microtubules are polymers of tubulin subunits (dimers) arranged on a hexagonal lattice. Each tubulin dimer comprises two monomers, the alpha-tubulin and beta-tubulin, and can be found in two states. In the first state a mobile negative charge is located into the alpha-tubulin monomer and in the second into the beta-tubulin monomer.

Force Sensor for Laparoscopic Babcock
1997General: A force sensor has been designed and fabricated that will fit to existing laparoscopic grasping forceps (Babcocks) from Ethicon Endosurgery Inc. The goal of the sensor development is to provide tool-tissue force information to the surgeons so that surgeons can regain the sense of touch that has been lost through laparoscopy.

Force Spectroscopy Several techniques can measure forces on biomolecules, but the need to connect the molecule to the macroscopic world often limits the rate at which data can be taken. Nickels et al. created large arrays of nanoscale force sensors by using DNA origami structures.

A magnetostrictive force sensor
Review of Scientific Instruments, 1994A new magnetostrictive force sensor is presented and its operation is verified experimentally. The sensor has a single excitation coil and a single detection coil, which utilize the magnetostrictive effect. The cores of the coils function as ‘‘spring elements’’ of the sensor, and are linked together by rigid end plates.

Novel Force Observer for Precise Force Estimation Using Force Sensor
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020Low frequency dynamic force offsets and measurement noises make utilization of force sensor signal a difficult task, especially, the direct feedback of force measurements in force control systems. To solve these force sensor problems, a novel Kalman filter-based force observer that automatically estimates and eliminates force sensor offsets and ...

Review of Scientific Instruments, 2005
Magnetization force acting on nonmagnetic materials has found wide uses as one of the applications that can be realized by a superconducting magnet. We propose a sensor that can measure the magnetization force three-dimensionally at a time. It consists of 24 Hall-effect magnetic sensors to define all the components of magnetic gradients needed to ...

There are several techniques to measure forces and pressures. Very often, the force to be measured is converted into a change in length or height of a piece of material, the spring element. The change in dimensions is subsequently measured by a sensor element, e.g. a (piezo-) resistive or resonant strain gauge or a changing capacitance.

The SI (Systeme International) unit of measurement for force F is the „Newton“ (N), which is one of the 7 base units of that system. In practice, large forces are usually expressed in kN (kilonewton) or MN (meganewton) while for small forces, the mN (millinewton) is used.
