Material Engineering for Environmental Applications

Dr. Suresh Valiyaveettil, Department of Chemistry, Faculty of Science, National University of Singapore, 3 Science Drive 3, Singapore, 117543.

Nano-science and nanotechnologies are expected to revolutionize our life in the coming years. Engineered nano-materials are already present in many consumer products. Such increased usage of nano-materials has caused concerns from various parts of our society, including government organizations and public in general. The main reason for such concern involves the lack of our knowledge on the fate of nano-materials inside a living organism. Recent studies have shown that metallic nano-particles are toxic to living systems. We have been examining such adverse impact of nano-materials in human cell lines and zebra-fish models.

On the other hand, if the environment is contaminated with nano-materials or other industrial pollutants, it is necessary to have efficient materials and methods to remove such pollutants from environment. Moreover, such technologies should be accessible to villages where large funding support may not be available for implementing water purification projects. Considering all these, we tried to develop new renewable adsorbents based on fruit peels or other cellulosic materials for water purification. My presentation will give full details on environmental impact of nano-materials and also look at the future remediation of contaminated environment.

Design and Development a Pneumatically Actuated Below Hip Orthosis for Partially Paralyzed Subjects

Dr. Sivanandan and Jobin Varghese, NIT Calicut

As per US Census Bureau, International Data Base, 2004, among 1,065,070,607 population in India, 7,455,494 are amputees. The number of amputees are increasing each and every year all over the world due to road accidents, diseases like Cerebral Palsy, Hereditary diseases, Brain Strokes, Body imbalance etc. Most of the victims of these incidents loses their mobility and they are being thrown from their peaceful and happier life to darkness. Mobility regaining is of prime concern for bringing back the amputees and paralyzed people back to their life. To attain this goal, it is necessary to develop an external structure which could support and assist the amputee or paralyzed people in their walking stage. Due to the continuous actuation of ankle, knee and hip joints, the probability of regaining the natural gait cycle is higher, when compared to the wheel chair mobility. Also it is equally important that the exoskeleton developed should be of low cost, so that any amputees irrespective of millionaire or pauper can make use of it.

Here we are engaged in developing a low cost Robotic Exoskeleton for actuation of below hip using pneumatic actuators. Initial Phase focuses on developing an exoskeleton with pneumatic actuators and use crutches for walking stability. Next phase focus on developing an exoskeleton which can perform walking without the help of crutches. We have designed a structure and current work going on for selecting an appropriate knee joint as well as actuator for the orthosis.

Wearable Human-Machine Interfaces

Dr. Sunil Sivadas, I2R, A*STAR, Singapore

Availability of low cost sensors in cellphones and wearables to measure human fitness and health, combined with advanced algorithms in machine learning triggered an innovation cycle in wearable interfaces. In recent times, this has spawned a few disruptive technologies that improved the quality of healthcare, reduced the cost of diagnosis and made certain science fiction into reality. In this talk we will have an overview of this vast and multi-disciplinary area.

Dr. Sunil Sivadas is a Scientist with Institute for Infocomm Research, A*STAR, in Singapore. He obtained his PhD from Oregon Graduate Institute, USA, M.Tech from Indian Institute of Science and B.Tech from N.S.S. College of Engg, Palakkad. He was a Member of Research Staff at Nokia Research Center, Finland, Visiting Scientist at International Computer Science Institute, Berkeley, USA. His research interests are in Machine Learning, Speech Recognition by machines and Computational models of Human Sensory Perception. He is interested in all things that make this world a better place.
