Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Background:

Conventional human-machine interfaces (HMIs) are limited by rigid electronics, hindering ductility and multifunctionality.
Artificial bionic skins offer potential but require improvements in mechanical properties, damage recovery, and environmental stability.
Current limitations lead to reduced service life and significant electronic waste.

Purpose of the Study:

To develop a novel artificial bionic skin with enhanced mechanical and sensory properties.
To address limitations in ductility, damage recovery, and environmental stability of existing bionic skins.
To create a sustainable and versatile HMI for advanced applications.

Main Methods:

Fabrication of a new artificial bionic skin with high strain tolerance (>13,000%).
Evaluation of environmental stability across a wide temperature range (-80 to 80 °C).
Integration of multisensory capabilities (strain, stress, temperature, solvent, bioelectricity) and assessment of damage reconfiguration and recyclability.

Main Results:

The bionic skin demonstrated exceptional mechanical performance and broad environmental stability.
It exhibited effective damage reconfiguration, recyclability, and multisensory detection.
The artificial bionic skin functioned effectively as an HMI for stimulus collection and differentiation.

Conclusions:

The developed artificial bionic skin overcomes limitations of conventional HMIs and current bionic skin technologies.
It offers a sustainable, high-performance solution for advanced interactive systems.
This innovation enables compliant, wireless human motion capturing and real-time robotic mimicry.
