Background:

Human skin's complex sensory receptors provide rich tactile and thermal information.
Replicating these natural sensory capabilities in artificial skin and prosthetics is a significant challenge.
Current smart prosthetics using rigid sensors have limitations in stretchability, detection range, and resolution.

Purpose of the Study:

To develop a highly stretchable and sensitive artificial skin for advanced prosthetic applications.
To integrate multiple sensing modalities (mechanical, thermal, humidity) and actuation (nerve stimulation) into a single prosthetic skin system.
To enhance the spatio-temporal resolution and detection range of artificial sensory feedback.

Main Methods:

Fabrication of ultrathin, single crystalline silicon nanoribbon arrays for strain, pressure, and temperature sensing.
Integration of humidity sensors, electroresistive heaters, and stretchable multi-electrode arrays for nerve stimulation.
Development of a flexible and stretchable substrate to house the sensor and actuator arrays.

Main Results:

Demonstrated highly localized mechanical and thermal perception mimicking human skin.
Achieved enhanced stretchability, detection range, and spatio-temporal resolution compared to existing technologies.
Successfully integrated diverse sensing and stimulation functionalities into a cohesive prosthetic skin system.

Conclusions:

The developed smart prosthetic skin represents a significant advancement in artificial sensory feedback.
This technology offers unique opportunities for next-generation prostheses with improved user experience.
The platform provides a versatile interface for peripheral nervous system research and applications.
