A Differential Volumeter for Micro-respiration Measurements

A Volumeter for Respiration of Aquatic Animals

A simple and innovative device to measure arm volume at home for patients with lymphedema after breast cancer.

PURPOSE We designed an arm volumeter specifically for home use based on the water displacement method. The objective of this study was to determine its accuracy and precision, and compare it with a standard volumeter used in lymphedema clinics worldwide. PATIENTS AND METHODS Using a standard model hospital volumeter and our own device, we took three consecutive measurements of 11 specially ca...

A New Simulation Model for Respiration Signal Measurements from Walking Human

There has been research interest in using the micro Doppler effect for contactless measurements of human respiration. Most of the research assumes that the test subject remains stationary. The purpose of this paper is to detect a respiration signal from a walking human. This work is at an early stage, and MATLAB model for a walking human with respiration movement was used, instead of recreating...

Dynamic modeling and nonlinear vibration simulation of piezoelectric micro-beam in self sensing mode of atomic force microscope

Nowadays, atomic force microscope is considered as a useful tool in the determination of intermolecular forces and surface topography with the resolution of nanometers. In this kind of microscope, micro cantilever is considered as the heart of the microscope and is used as a measuring tool.  This paper is aimed towards investigating the behavior of a piezoelectric micro cantilever with a triang...

Aging Decreases Hand Volume Expansion with Water Immersion

Hands may show early signs of aging with altered skin texture, skin permeability and vascular properties. In clinics, a hand volumeter is used to measure swelling of hands due to edema, carpal tunnel syndrome or drug interventions. The hand volume measurements are generally taken without taking age into consideration. We hypothesized that age affects hand volumeter measurements and that the you...
