Looking for the physical properties of the skin

Click For Summary

Discussion Overview

The discussion revolves around the physical properties of skin, specifically seeking equations and data related to its structure, such as impedance, heat conduction, dielectric coefficient, and magnetic permeability. Participants are looking for resources beyond typical biology texts, indicating a focus on biophysics and applied physics aspects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses difficulty in finding useful information in biophysics and physiology books regarding the physical properties of skin.
  • Another suggests that researchers in prosthetics or biomechanics might have relevant data due to thorough data collection practices.
  • Concerns are raised about the variability of skin properties across different body parts, which complicates the search for consistent data.
  • A participant humorously references historical experiments related to skin properties, though the validity of those works is questioned.
  • There are suggestions to consider elasticity theory and to approximate skin properties as similar to water for simplification.
  • One participant notes the challenge of achieving a stationary state for certain calculations related to skin properties.
  • A later reply mentions the desire to conduct basic research before consulting an expert, emphasizing the need for foundational knowledge to formulate appropriate questions.
  • It is suggested that expertise in this area may be limited, with few individuals possessing substantial knowledge.

Areas of Agreement / Disagreement

Participants express uncertainty about the availability of data and the variability of skin properties, indicating that multiple competing views remain regarding the accessibility and consistency of information on this topic.

Contextual Notes

Limitations include the variability of skin properties across different body parts and the potential lack of published research on the specific physical properties being sought.

ive been searching through many biophysics and physiology books lately... but i haven't found anything useful... i want to find some explanations of the structure of the skin - but not the ones you'd get from biology books - i want equations that describe the impedance of each layer of the skin, heat conduction, dielectric coefficient, magnetic permeability.. these sort of things.

anyone knows where i could learn about it?

No real clue. All that I can think of right now is that perhaps researchers working on prosthetics or biomechanics related to sports performance might have that sort of stuff in their files. They tend to be pretty thorough about data collection.
 
You won't find a lot of data, since there's such variability in nature, and no manufacturing process control of which to speak. Also, the properties vary vastly depending on the body part; compare the skin on the heel of your foot to that on your eyelid.

If you do manage to find anything, please post back and let me know.
 
I'm sure Mengele tried to determine these properties with some real-life experiments..

I'm not sure his work was published...!

You should get into elasticity theory. :biggrin:
 
Probably the easiest approximation that you can use it to treat it as water.

Umm, so I guess that makes [tex]\frac{p}{\rho g} + \frac{v^2}{2g}+z[/tex] constant along the same wrinkle? :biggrin:
 
Only if you are in a STATIONARY sweaty state, which seems somewhat difficult to achieve, but I am digressing..shut up myself.

yes, i thought about finding one, but i wanted to do some basic research of my own before i talk to an expert in the field... when you know almost nothing you don't have the right questions.

I suspect, though, that this might be an area where there's no 'in-between'. Anybody who knows anything about it probably is an expert.
