Contact Lens-Based Intraocular Pressure Sensor
Engineering Proceedings, 2023 The intraocular pressure (IOP) is the principal indicator for diagnosis of glaucoma which is one of the leading causes of blindness. The IOP can vary throughout the day, and traditional methods of measuring it in a clinical setting only provide a ...

Effect of Interference Size on Contact Pressure Distribution of Railway Wheel Axle Press Fitting
Designs, 2023 Mechanical couplings in engineering usually use interference fits to connect the shaft and hub. A railway wheel axle is a press fit that is connected by interference and can be subjected to bending stress.

Pressure eye: In-bed contact pressure estimation via contact-less imaging
Medical Image Analysis, 2023 Computer vision has achieved great success in interpreting semantic meanings from images, yet estimating underlying (non-visual) physical properties of an object is often limited to their bulk values rather than reconstructing a dense map. In this work, we present our pressure eye (PEye) approach to estimate contact pressure between a human body and ...

Use of 3D scanning technique to determine tire deformation in static conditions
Journal of Agricultural Engineering, 2022 This paper presents an innovative digital method to analyse agricultural tire profiles based on pictures. From this method, we can conclude that the tire deformation is caused by the changes in vertical load and inflation pressure.

Contact pressure–aided spectroscopy [PDF]
Journal of Biomedical Optics, 2014 Contact pressure induced by manually operated fiber optic probes can significantly affect the optical properties of the studied tissue. If the contact pressure and the changes in optical properties are measured properly, then the complementary information can be used to obtain additional insight into the tissue physiology.
