Phase Transitions02:31

Phase Transitions

23.3K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Intermolecular vs Intramolecular Forces03:00

Intermolecular vs Intramolecular Forces

97.8K
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...

Phase Transitions: Sublimation and Deposition02:33

Phase Transitions: Sublimation and Deposition

20.3K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

Phase Transitions: Melting and Freezing02:39

Phase Transitions: Melting and Freezing

15.3K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Phase Diagrams02:39

Phase Diagrams

50.4K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

Intermolecular Forces03:13

Intermolecular Forces

71.9K
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...

Area of Science:

  • Biomechanics
  • Wearable technology
  • Biomedical engineering

Background:

  • Quantitative gait analysis is vital for profiling, diagnosing abnormalities, and planning rehabilitation.
  • Accurate gait phase determination is essential for effective gait analysis.
  • Force myography (FMG) offers a potential non-invasive method for gait monitoring.

Main Methods:

  • A custom force myography band was developed and tested on nine participants walking on a treadmill.
  • Force myography data were analyzed sample-by-sample and classified into four gait phases using Linear Discriminant Analysis.
  • Gait phase events were detected using a set of supervisory rules applied to classified data.

  • The force myography band achieved over 99.9% accuracy in detecting gait phases across 12,965 segments.
  • The system demonstrated minimal error, with zero insertions and only four deletions.

Conclusions:

  • Force myography is a feasible technique for developing wearable gait phase detection systems.
  • The developed system shows high potential for clinical applications in gait analysis and rehabilitation.
  • This proof-of-concept study validates FMG as a viable solution for wearable gait monitoring.
