Context
A new study has now shown that how the ridges and the skin moisture help human.
How it is useful?
- Due to the sweat glands and ridges a greater levels of grip develops when holding on to objects.
- Monkeys, apes and we humans have evolved fingerprints or ridges on hands and feet.
- This region on our hands and feet also has a high density of sweat glands.
- Fingerprint ridges help increase the friction and the sweat is also regulated to maximise friction.
- This dual-mechanism gave them manipulative and locomotor abilities not available to other animals, such as bears and big cats.
- How the study is significant?
- It will help in understanding the influence of finger pad friction that will help to develop more realistic tactile sensors.
- It will be significant for the applications in robotics and prosthetics and haptic feedback systems for touch screens and virtual reality environments.
