Wirelessly powered miniature wearable vital signs monitor

Marzencki M., Kaminska B., Simon Fraser University, CA

In this work, we propose a novel system that employs a long range inductive link to recharge a small battery on-board a wearable device. One end of the link is integrated into the wearable device [...]

Preparation of nickel doped multi-functional micro-patternable polydimethylsiloxane nanocomposite polymer with characterization of its magnetic, electrical and mechanical properties for soft MEMS/Lab on a chip applications

Khosla A., Korand J.L., Haiducu M., Gray B.L., Leznoff D.B., Parameswaran M., Simon Fraser University, CA

We present the preparation and characterization of a novel polydimethylsiloxane (PDMS) multifunctional nanocomposite with electric and magnetic properties. The composite is fabricated by ultrasonic agitation of nickel nanoparticles in the PDMS matrix. The prepared nanocomposite [...]

Monitoring of the major blood vessels supplying head and brain (carotid arteries) contactlessly

Kaminska B., Simon Fraser University, CA

An apparatus for measuring Carotid Arteries movement without physically connecting electrodes or other sensors to the body was developed. The measurement system was implemented to simultaneously monitor the Carotid Arteries and ECG in order to [...]

Multi-functional Wearable Device for Heart Health and Possition Assesment

Kaminska B., Simon Fraser University, CA

In this paper we introduce a wearable device combining physiological monitoring and person’s position assessment. An accelerometer is used as a multi-functional sensor for a position and heart mechanical performance measurements, known as mechanocardiography (MCG). [...]

Wireless Micro and Nano Sensors for Physiological and Environmental Monitoring

Kaminska B., Simon Fraser University, CA

A wearable physiological/environmental monitoring system and a practical implementation are presented. The technical requirements for wearable electronics and sensors have been specified with an example of ECG, oxygenometer, and wireless network-based bidirectional communication. A presented [...]

Prevention and Risk Reduction in Heart Health

Kaminska B., Tavakolian K., Ngui B., Chuo Y., Carmichael B., Simon Fraser University, CA

Identifying early onset of cardiac disease is not easy and it is very expensive. For this reason the first symptom of cardiac problems is often catastrophic. It is the goal to produce a low cost [...]

Symbolic Finite Element Analysis for Parametric Studies

Johnstone R.W., Shimizu T., Parameswaran M., Simon Fraser University, CA

In our paper, we will present a method of performing finite element analysis using a symbolic kernel. The representation of numbers used in analysis is symbolic expressions instead of floating point numbers. Unlike standard finite [...]

Reflow Microfabrication for Refractive Optical Components: Process and Materials

Johnstone R.W., Parameswaran M., Simon Fraser University, CA

Our paper will describe a new method of fabricating refractive optical components for free-space micro-optical systems. The seminal paper on this topic was Pister et al [1], in which hinges were used to demonstrate several [...]
