Background Subsurface mechanisms can greatly affect the mechanical behavior of
biological materials, but observation of these mechanisms has remained elusive primarily …

In breast cancer diagnosis and therapy monitoring, there is a need for frequent, noninvasive
disease progression evaluation. Breast tumors differ from healthy tissue in mechanical …

The mechanical and optical characteristics of a transparent tissue surrogate ballistic polymer
gel were measured at different loading rates. This included measurement of tension and …

Early detection of breast cancer will continue to be crucial in improving patient survival rates
for the foreseeable future. Our long-term goal is to automate and refine the manual breast …

A spherical inclusion is embedded in a soft gel block. A vertical force is applied on the gel
surface by means of a spherical indenter. The loading axis is not aligned with the inclusion …

Early detection of breast cancer will continue to be crucial in improving patient survival rates.
Our ultimate goal is to develop an electro-mechanical device to automate and refine the …

A rigid inclusion is embedded at a finite depth in a soft layer resting on a rigid substrate. A
spherical indenter presses vertically onto the surface, deforming the matrix and displacing …

A solid inclusion is embedded at a depth in a hyperelastic soft matrix resting on a rigid
substrate. External compression is applied via an indenter vertical to the substrate, but the …

Indentation technique for the mechanical evaluation of soft materials like biological tissue is
discussed in order to develop the medical device of palpation. Here, the Hertzian contact …

The incidence rate of breast cancer for women in Japan is increasing each year. The three
main methods of screening for breast cancer are finger palpation, mammography and breast …
