Skin Variations Impact on Non-Invasive Measurement of Blood Glucose with Interdigital Electrodes

J. Persad [1], S. Rocke [1],
[1] Department of Electrical and Computer Engineering, University of the West Indies, St. Augustine, Trinidad and Tobago

This work aims to investigate the behaviour of a simple interdigital sensor structure for glucose monitoring in response to distortions in the skin-topology and differences in skin undulation during use. The study then extends to consider a flexible sensor structure which is better able ... Read More

Designing the Actuator for the Next-Generation Astronomical Deformable Mirrors: a Multidisciplinary and Multiphysics Approach

C. Del Vecchio[1], R. Biasi[2] , D. Gallieni[3], and A. Riccardi[1]

[2]Microgate Srl, Bolzano, Italy
[3]ADS International Srl, Valmadrera, Italy

The actuation system of the deformable mirror is one of the crucial components of an Adaptive Optics unit. One possible implementation comprehends a linear force motor and a capacitive sensor providing the feedback measure signal. Choosing a magnetic circuit that makes optimum use of the ... Read More

MEMS Based Tactile Sensors for Robotic Surgery

V. Nivethitha[1], S. P. Rakavi[1], K. C. Devi[1]
[1]PSG College Of Technology, Coimbatore, Tamil Nadu, India

In this work, a piezoelectric tactile sensor will be designed and simulated using COMSOL Multiphysics®. The sensor is designed in order to assess the pressure exerted on the human body while the robotic surgery is performed. The sensor consists of a rigid and compliant cylindrical ... Read More

Flow and heat transfer simulations as a development tool for a novel microcalorimeter

C. Fricke¹, T. Klee², S. Richter², S. Paufler¹, H. Harms¹, T. Maskow¹
¹Helmholtz Centre for Environmental Research – UFZ, Leipzing, Germany
²Loetec Elektronische Fertigungssysteme GmbH, Lutherstadt Wittenberg, Germany

Calorimetry is the method of choice for determining one of the most elementary physical quantities: heat, Q [in J]. Depending on the individual issue a wide range of techniques, devices and methods are available for users [1]. One approach is called isothermal microcalorimetry (IMC). It ... Read More

Multiphysics Simulation of the Effect of Sensing and Spacer Layers on SAW Velocity

P. Zheng[1,4], D.W. Greve[2,4], and I.J. Oppenheim[3,4]

[1]Department of Physics, Carnegie Mellon University, Pittsburgh, Pennsylvania, USA
[2]Department of Electrical and Computer Engineering, Carnegie Mellon University, Pittsburgh, Pennsylvania, USA
[3]Department of Civil and Environmental Engineering, Carnegie Mellon University, Pittsburgh, Pennsylvania, USA
[4]National Energy Technology Laboratory, Pittsburgh, Pennsylvania, USA

Surface acoustic wave gas sensors use a chemically sensitive resistive layer to detect gas concentration. The resistivity of the sensing material, the sensing layer thickness, and the spacer layer thickness all affect the surface wave propagation velocity. Existing analytic theory ... Read More

Design and Simulation of MEMS Anemometer

D. Tandon [1], N. Kothari [1],

[2] Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Carbon Steel pipes are used as feeder pipes in Pressurized Heavy Water Nuclear Reactors for carrying the coolant from the inlet headers to the coolant channel and again from outlet of the coolant channel to the outlet headers and are part of the Primary Heat Transport (PHT) System of ... Read More

Development of a RheoDSC, an Instrument for Simultaneous Rheological and Calorimetric Measurements

L. Van Lokeren [1], R. Verhelle [1], C. Block [1], P. Van Puyvelde [2], G. Van Assche [1]
[1] Vrije Universiteit Brussel, Brussels, Belgium
[2] Catholic University of Leuven, Leuven, Belgium

Transformations in polymers, such as polymerisation, melting/crystallization, and phase separation/remixing, are associated with changes in both rheological and thermal properties. To permit simultaneous calorimetric and rheometric measurements, the RheoDSC was developed. The RheoDSC ... Read More

Frequency Dependent UEP Signatures of Naval Vessels Modeled by a Current Dipole

C. Broecheler [1], Ch. Thiel [1], A. Rennings [1], F. Ludwar [2], J. Doose [2], D. Erni [1],
