Research Overview

VM Technology is currently collaborating with the The New York University Center for Urban Science And Progress (NYU CUSP) and with the NYU Civil and Urban Engineering Department on research, development and implementation of innovative, flexible, scalable, reliable and affordable sensing solutions for various applications, with the emphasize on infrastructure degradation. VM Technology is led by Cristian Vimer, PhD, PE, who has been involved for more than eighteen years in this research and he has published several articles in specialty journals and trade magazines. See here a detailed Curriculum Vitae and his Google Scholar profile.

Since 2000, we have been exploring a few directions of development: fiber optic sensing for detection of chemicals, optical imaging for corrosion detection and vibration monitoring for structures and equipment. We use the latest advances in nanotechnology in order to develop fully integrated wireless sensing networks, with simultaneous real-time high speed data acquisition, transmission and analysis.

Wireless sensor networks consists of spatially distributed autonomous sensors (for both physical and chemical parameters) that cooperatively pass their data through the network to the main location; also, through the same network we can control the activity of the sensors. Data harvested by the various sensors is transmitted through the network nodes (small basic “computers” that consist of processing units - Micro-Electro-Mechanical Systems, or MEMS - micro radio transceivers, and power sources that use energy harvesting modules for solar power) and it is stocked and remotely analyzed. During the years, our research has been funded by the National Science Foundation, the NY State Department of Transportation, the construction and energy industry, and by various international agencies.

Results of this research have been summarized in a book published in 2018 by Springer Publishing - “Optical Phenomenology and Applications: Health Monitoring for Infrastructure Materials and the Environment” (volume 28 in the series “Smart Sensors, Measurement and Implementation”). This book was coordinated by Masoud Ghandehari, PhD of NYU CUSP and a professor on the Faculty of Civil and Urban Engineering Department at the NYU Tandon School of Engineering and published.

This book is an introduction to techniques and applications of optical methods for materials characterization in civil and environmental engineering. It describes the utility of optical-sensing technologies in applications that include monitoring of transport processes and reaction chemistry in materials of the infrastructure and the subsurface environment. Many of the applications reviewed will address long standing issues in infrastructure health monitoring such as the alkali silica reaction, the role of pH in materials degradation, and the remote and inset characterization of the subsurface environment. Application of optical wave-guides and full field imaging for civil and environmental engineering application is introduced and chemical and physical recognition strategies are presented; this is followed by range of filed deploy-able applications. Emphasizing system robustness, and long-term durability, examples covered include in-situ monitoring of transport phenomena, imaging degradation chemistry, and remote sensing of the subsurface ground water. Cristian Vimer is co-author of five chapters.
