- Feeling small: Fingers can detect nano-scale wrinkles even on a . . .
In a ground-breaking study, Swedish scientists have shown that people can detect nano-scale wrinkles while running their fingers upon a seemingly smooth surface The findings could lead such
- Your Fingernails Have Unexpectedly Precise Sensory Capabilities
Pacinian corpuscle mechanoreceptors lie deep within the second-last layer of our skin, the dermis These nerve endings detect patterns of vibrations across widespread regions of our skin, allowing us to understand the tactile location of tools
- What is the smallest touch sensation that a human can feel?
Johansson Valbo (1970) investigated static detection thresholds on the palm of the hand (Fig 1) and found average thresholds of 10 to 40 micrometers indentation This variation was due to geographical differences; towards the fingers sensitivity is higher and thresholds are hence lower (Fig 2) Fig 2
- TIL that the human fingertip can feel the difference between a smooth . . .
You heat but there's actually a 'fingernail' test in aerospace It's used to define if there's 2 much off a ridge between 2 adjacent paint jobs I think If you can feel it with your finger nail, it goes back to the paint shop!
- Effect of fingernail length on the hand dexterity - PMC
The length of the fingernail was defined as the greatest longitudinal distance from the groove at the junction of the eponychium and proximal nail fold to the tip of the finger The width of the fingernail was defined as the greatest transverse distance between the two lowest points of the fingernail in the lateral nail groove
- Human Touch Detects Objects Smaller Than Bacteria: Nanoscale . . .
Your sense of touch is way more sophisticated than you can imagine A new study indicates that our tactile capacity extends far beyond our visual range, allowing us to detect objects on the nanoscale Researchers believe that the findings may inspire new developments in a wide variety of fields
- Study of human tactile perception shows how sensitive touch is - UPI
The human finger can discriminate between surfaces patterned with ridges as small as 13 nanometers in amplitude and non-patterned surfaces, surface chemistry Professor Mark Rutland said
- Let Your Fingers Do the Seeing - National Geographic
When your finger rubs against another surface, tiny pressure sensors embedded within your fingers, called Pacinian corpuscles, perceive the texture These sensors also pick up vibrations, and
