The mechanical properties of skin are important for a number of applications including
surgery, dermatology, impact biomechanics and forensic science. In this study, we have …

Microscale surgery on single cells and small organisms has enabled major advances in
fundamental biology and in engineering biological systems. Examples of applications range …

With the development of science and technology, the surgical blade cutting soft tissue
continuously improves the design of blade to meet the higher technical requirements of …

The sharpness of a blade is a key parameter in cutting soft solids, such as biological tissues,
foodstuffs or elastomeric materials. It has a first order effect on the effort, and hence energy …

In the machining of traditional metallic materials, high hardness is primary property that tool
designers are committed to pursuing to improve wear resistance. In this study on machining …

In line with engineering research focusing on metal tools, techniques to record the attribute
of 'edge sharpness' on stone tools can include both mechanical and micro-geometric …

Simple flake cutting tools were utilized across broad chronological and geographical ranges
during prehistory. Fundamental to their functional utility is the presence of a relatively acute …

Biological puncture systems use a diversity of morphological tools (stingers, teeth, spines
etc.) to penetrate target tissues for a variety of functions (prey capture, defence …

Herbivores large and small need to mechanically process plant tissue. Their ability to do so
is determined by two forces: the maximum force they can generate, and the minimum force …

Although the sharpness of a blade is responsible for cutting performance, there is no single
and unambiguous literature definition of sharpness. The blade sharpness index (BSI) …
