The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.0K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Introduction to Special Senses

7.5K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

Electron Carriers01:24

Electron Carriers

91.7K
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons.
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Tactile and Chemical Senses01:27

Tactile and Chemical Senses

791
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Electron Behavior00:54

Electron Behavior

108.2K
Overview
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Biomedical Engineering

Background:

  • Electronic skin (e-skin) is crucial for artificial intelligence, aiming to replicate or surpass human skin functions.
  • Current e-skin often uses polydimethylsiloxane (PDMS), which is not ideal for long-term wear due to poor air permeability.
  • Leather offers natural comfort and sophisticated structure, but lacks inherent sensing capabilities.

Purpose of the Study:

  • To create a novel, breathable, and comfortable e-skin using leather as a substrate.
  • To integrate nanomaterials into leather to impart multifunctional sensing properties.
  • To explore new material classes for advanced e-skin development.

Main Methods:

  • A simple and designable method was employed to merge leather's properties with nanomaterials.
  • Leather was repurposed to incorporate sensing capabilities, transforming "dead skin" into functional e-skin.
  • The developed e-skin was evaluated for its potential in various applications.
