Sensory Functions of the Skin

Sensory Functions of the Skin

The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Tactile and Chemical Senses

Tactile and Chemical Senses

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. This...

Background:

Intelligent robotic devices require enhanced liquid perception for autonomous regulation in droplet environments.
Current electronic skins (e-skins) struggle to realistically perceive and provide timely feedback on liquid sliding behavior.

Purpose of the Study:

To develop a self-powered bionic electronic skin capable of comprehensive and realistic liquid information detection.
To overcome the limitations of existing e-skins in perceiving dynamic droplet behaviors.

Main Methods:

Constructed an ingenious co-layer interlaced electrode network with an overpass connection method.
Utilized triboelectricity to convert dynamic droplet sliding behaviors into electrical signals.
Developed a system for real-time visual feedback of two-dimensional droplet sliding.

Main Results:

The bionic e-skin successfully perceives various dynamic droplet sliding behaviors and converts them into electrical signals.
Achieved comprehensive two-dimensional sliding behavior perception with real-time visual feedback.
Demonstrated flow direction warning and intelligent closed-loop control of water leakage.

Conclusions:

The proposed bionic droplet electronic skin significantly enhances robotic perception in liquid environments.
This technology bridges the gap between artificial and human skin in droplet sensing capabilities.
The e-skin offers advanced functionalities like flow warning and intelligent water leakage control.
