Strain and Elastic Modulus

Strain and Elastic Modulus

The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...

Background:

Soft and stretchable strain sensors are crucial for health monitoring, motion tracking, and robotics.
There's a growing need for strain sensors in amphibious environments, including implantable, wearable (for swimmers/divers), and underwater robotic applications.
Developing sensitive, stretchable, and robust amphibious strain sensors remains a significant challenge.

Purpose of the Study:

To present a novel encapsulated stretchable amphibious strain sensor.
To investigate the effects of cut design and interfacial interactions on sensor performance.
To demonstrate the sensor's functionality in diverse amphibious applications.

Main Methods:

Fabrication of a stretchable sensor using silver nanowires embedded in polydimethylsiloxane, sandwiched by thermoplastic polyurethane.
Introduction of periodic sharp cuts to control crack propagation and conductive pathways.
Characterization of sensor performance, including gauge factor, response time, robustness, and stability in saline solution.

Main Results:

The sensor achieved a high gauge factor (up to 289) with a linear response and fast response time (53 ms).
Demonstrated excellent robustness against over-strain and stability over 16,000 cycles and 20 days in saline solution.
Successfully applied in tracking robotic fish motion, underwater language recognition, and porcine aorta blood pressure monitoring.

Conclusions:

The developed encapsulated stretchable sensor meets the demands for amphibious applications.
Its high performance and durability show significant promise for underwater sensing and surgically implantable devices.
This work paves the way for advanced sensing in challenging aquatic and biomedical environments.
