Introduction The study of bio-inspired materials and surfaces has been a rapidly growing area of research in recent years [1], focusing on creating new and improved materials that mimic the structures and functions of natural materials.
Absorptance is essential in various engineering and materials science applications, including solar panels, energy-efficient windows, optical coatings, and filters.
This property is crucial in various engineering and materials science applications, including optical filters, lenses, transparent conductors, solar panels, and energy-efficient windows.
In engineering and materials science, friction is a critical factor in many applications.
A differential characteristic of 3D printing is a wider applicability for different materials (ceramic, metal, or polymeric phases) and even for hybrid materials.

To implement the power self-generate function, we make an important change on the component of leaf springs which we setting piezoelectric materials on both sides of the spring.
With vibration of leaf springs, mechanical vibration energy will transform to pressure on piezoelectric materials and therefore micro-current will be came into being.

Therefore, the understanding of reloading stress relaxation behavior of structural materials is required for safety designing and maintenance of steam-powered plants[1,2].
Material parameters γ, δ can be identified by fitting the experimental residual stress curves while other material parameters are available.
