Tactile and Chemical Senses01:27

Tactile and Chemical Senses

795
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.

Predator-Prey Interactions02:39

Predator-Prey Interactions

21.6K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Van der Waals Interactions01:24

Van der Waals Interactions

71.4K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

piRNA - Piwi-interacting RNAs

7.7K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Drug-Receptor Interactions01:29

Drug-Receptor Interactions

7.5K
Drug-receptor interaction describes the binding of receptors by drugs, but not all drug-receptor interactions result in activation and tissue response. For instance, the binding of agonists activates the receptor to generate a cellular reaction, while antagonists bind to receptors without causing their activation.
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue....

Gene-Environment Interactions01:20

Gene-Environment Interactions

1.2K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Area of Science:

  • Human-Computer Interaction
  • Materials Science
  • Wearable Technology

Background:

  • Physical buttons offer tactile feedback but lack interface flexibility.
  • Touchscreens provide flexibility but lack tactile qualities for vision-free use.
  • A need exists for interfaces combining dynamic flexibility with tactile feedback.

Purpose of the Study:

  • To introduce a novel stretchable display capable of dynamic shape change.
  • To integrate light emission and touch sensing into a single, flexible device.
  • To enable vision-free interaction through combined visual and haptic feedback.

Main Methods:

  • Developed hyperelastic light-emitting capacitors (HLECs) for the stretchable display.
  • Characterized device performance, including stretch, luminance, and pressure sensitivity.
  • Integrated co-located touch sensing and light-emitting capabilities.

Main Results:

  • The display successfully changes shape from a flat sheet to a dome upon pressurization.
  • HLEC panels exhibit pressure-dependent luminance, visually indicating press location.
  • Demonstrated interactive capabilities with a memory game showcasing integrated functions.

Conclusions:

  • The stretchable HLEC display offers a novel approach to dynamic, tactile interfaces.
  • The pressure-dependent luminance provides visual cues for haptic information.
  • This technology has potential applications in areas requiring vision-free interaction.
