Osmoregulation in Fishes02:32

Osmoregulation in Fishes

52.9K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Mechanism of Breathing I: Inspiration

3.1K
Introduction to Inspiration: The Respiratory System in Action
The respiratory system, an essential network for breathing, comprises the conducting and respiratory zones, each playing a crucial role in the overall process of respiration. Let us explore the detailed mechanism of inspiration, or inhalation, which is the first phase of the respiratory cycle.
Pathway of Air during Inspiration
During inspiration, air enters our body through the nose or mouth and moves through the conducting zone,...

Definition and Measurement of Pressure: Atmospheric Pressure, Barometer, and Manometer

42.7K
Gas pressure is caused by force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small, any surface of an appreciable area experiences a large number of collisions in a short time, which can result in high pressure.

Lateralization01:28

Lateralization

983
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Difference from Background: Limit of Detection01:05

Difference from Background: Limit of Detection

8.1K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Electric Potential and Potential Difference01:16

Electric Potential and Potential Difference

5.6K
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...

Area of Science:

  • Biomimetics and Sensor Technology
  • Fluid Dynamics and Hydrodynamics

Background:

  • The lateral line system in fish provides effective flow sensing capabilities.
  • Existing underwater sensors often lack the sensitivity and adaptability of biological systems.

  • Design and fabrication of a fish canal lateral line-inspired sensor using an ionic polymer-metal composite (IPMC) within a fluid-filled canal with a latex membrane.
  • Experimental characterization of the sensor's output by rotating a fish-like body relative to a dipole source.
  • Finite element modeling (FEM) to simulate fluid-structure interactions and IPMC physics.

Main Results:

  • The sensor successfully captured pressure differences between its two pores when subjected to flow.
  • Experimental data validated the sensor's ability to detect changes in pressure gradients.
  • FEM simulations provided insights into the sensor's operational principles and fluid-structure dynamics.

Conclusions:

  • The developed fish lateral line-inspired sensor is capable of detecting pressure differences, mimicking biological systems.
  • The sensor shows potential for enhancing underwater robotics through applications such as object detection, angle of attack measurement, and source localization.
  • The study demonstrates the utility of the sensor in enabling underwater robots to orient themselves towards a source using sensor feedback.
