Fiber-Optic Fabry-Pérot Interferometers for Axial Force Sensing on the Tip of a Needle
Sensors, 2016 A range of complex percutaneous procedures, such as biopsy or regional anesthesia, rely heavily on accurate needle insertion. Small variations in the mechanical properties of the pierced tissue can however cause deviations from the projected needle path ...

Colloids, polymers, and needles: Demixing phase behavior
, 2001 We consider a ternary mixture of hard colloidal spheres, ideal polymer spheres, and rigid vanishingly thin needles, which model stretched polymers or colloidal rods.

New double indentation technique for measurement of the elasticity modulus of thin objects [PDF]
, 2011 In this paper we introduce a new method to determine the Young's modulus of thin (biological) samples. The method is especially suitable for small objects with a thickness of a few hundred micrometers.

Investigation of vibration parameters for needle insertion force reduction
Current Directions in Biomedical Engineering, 2020 Many medical interventions in therapy and diagnostics require needle insertion into tissue. Common complications such as increased pain and formation of haematoma are caused by wrong needle positioning.
