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).

Recent advances in non-contact force sensors used for micro/nano manipulation

Sensors and Actuators A: Physical, 2019
Micro/nano manipulation for both mechanical and biological structures is currently a popular research field. To protect small-scale structures and acquire their mechanical properties, a micro-scale force sensor is needed.

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.

Quantifying molecular tension—classifications, interpretations and limitations of force sensors

Physical Biology, 2019
Molecular force sensors (MFSs) have grown to become an important tool to study the mechanobiology of cells and tissues. They provide a minimally invasive means to optically report mechanical interactions at the molecular level.

Force-Sensitive Prosthetic Hand with 3-axis Magnetic Force Sensors

IEEE International Conference on Cyborg and Bionic Systems, 2019
In this paper, we investigate the use of 3-dimensional (3D) force sensors in a prosthetic hand. 3D force sensing in prostheses can be used to incorporate intelligent grasping capabilities, allowing the hand to automatically adjust its grasp or release an

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.

Piezoelectric force sensor for scanning force microscopy

Sensors and Actuators A: Physical, 1994
Abstract A dynamic scanning force microscope using a piezoelectric force sensor has been constructed. The complexity of the conventional dynamic SFM is due to the detector used for measuring the vibration amplitude of the cantilever. Our sensor enables direct detection of signals related to the lever amplitude by a piezoelectric layer formed on the ...

Accuracy and precision of loadsol® insole force-sensors for the quantification of ground reaction force-based biomechanical running parameters

European Journal of Sport Science, 2018
Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for ...
