MEG-compatible force sensor

Journal of Neuroscience Methods, 2005
By use of an insulating material we constructed a strain gauge based sensor to measure isometric forces in parallel with magneto-encephalographic recordings (i.e. without interference). The sensor can be used in different geometries to measure force production in different dimensions.

Magnetization force sensor

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 ...

Miniature all-fiber force sensor

Optics Letters, 2020
A miniature all-fiber Fabry–Perot sensor for measurement of force is presented in this Letter. The sensor consists of a thin silica diaphragm created at the tip of the fiber. The central part of the diaphragm is extended into a silica pole, which is ended with a round-shaped probe or a sensing cylinder apt for asserting measured force.

Many tiny force sensors

Science, 2016
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.

Note: Helical nanobelt force sensors

Review of Scientific Instruments, 2012
We present the fabrication and characterization of helical nanobelt force sensors. These self-sensing force sensors are based on the giant piezoresistivity of helical nanobelts. The three-dimensional helical nanobelts are self-formed from 27 nm-thick n-type InGaAs/GaAs bilayers using rolled-up techniques, and assembled onto electrodes on a micropipette

DNA: A Programmable Force Sensor

Science, 2003
Direct quantification of biomolecular interaction by single-molecule force spectroscopy has evolved into a powerful tool for materials and life sciences. We introduce an approach in which the unbinding forces required to break intermolecular bonds are measured in a differential format by comparison with a known reference bond (here, a short DNAduplex).

Microtubules as mechanical force sensors

Biosystems, 2007
Microtubules 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

1997
General: 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.
