Compact Bone01:27

Compact Bone

17.0K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Compacting Factor test01:22

Compacting Factor test

606
The compacting factor test is a method used to assess the workability of concrete. It is  especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...

Intermolecular Forces03:13

Intermolecular Forces

72.4K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Electromotive Force02:36

Electromotive Force

30.3K
Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled  that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc  with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one substance to...

Intermolecular vs Intramolecular Forces03:00

Intermolecular vs Intramolecular Forces

98.0K
Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

Intermolecular Forces in Solutions02:28

Intermolecular Forces in Solutions

40.1K
The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Area of Science:

  • Robotics
  • Biomechanics
  • Assistive Technology

Background:

  • Seniors often experience muscle weakness, leading to difficulties in walking.
  • Hip-mounted exoskeletons can provide assistance but require accurate force monitoring for effective and safe operation.
  • Previous methods estimated hip assistance force indirectly, limiting control precision.

Purpose of the Study:

  • To propose and validate a compact force sensor system for hip-mounted exoskeletons.
  • To enable direct measurement of interaction forces between the exoskeleton and the user's lower limb.
  • To enhance motion control and safety features of assistive walking devices.

Main Methods:

  • Development of a compact force sensor system utilizing two force-sensitive resistor (FSR) sensors.
  • Design of a force sensing structure to isolate and measure hip-motion-induced forces.
  • Integration of the sensor system onto a hip-mounted exoskeleton prototype attached to a thigh frame.

Main Results:

  • The proposed sensor system directly measures the hip assistance force, unlike indirect estimation methods.
  • The system allows for the generation of torque based on direct force measurement, enabling precise control of delivered power and torque.
  • Experimental validation confirmed the successful measurement of hip assistance force with the prototype sensor.

Conclusions:

  • The compact force sensor system offers a direct and accurate method for measuring interaction forces in hip exoskeletons.
  • This technology improves the control capabilities and safety of assistive devices for individuals with walking impairments.
  • The developed system represents a significant advancement in wearable robotics for geriatric mobility assistance.
