Biometrics – the techniques for authentication which rely on measurable characteristics that can be automatically checked. Different aspects of biometrics include biometric data, matching and verification. Biometric identification (video 1:55) – Biometric screening is being used increasingly across the world as authorities and travel operaters attempt to boost security and clamp down on identity fraud. face recognition – uses images of a person’s face for recognition and identification. voice recognition – computer systems that can recognize spoken words. Voice recognition can take dictation, but does not understand what is being said. eye track – a combination of an eye-tracker device … Continue reading biometrics


biofeedback – process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and pain perception. Biofeedback may be used to improve health, performance, and the physiological changes that often occur in conjunction with changes to thoughts, emotions, and behavior. smart glasses – electrooculography sensors have been set into the frame of the glasses; above the nose and on the nose pads. … Continue reading biofeedback

watering small vegetable garden plot Engineers work to make solutions to solve human needs. Many engineered solutions benefit humanity in ways we take for granted. Life would be different without clean running water, flush toilets, comfortable houses, cars and the roads to drive on. The water pump, flush toilet, air conditioning, electric vehicles, road construction are just a few examples of engineering solving human needs. Engineering & Society – Engineers contribute to the development of many innovations that improve life. We investigate how engineers work to meet human needs and great engineering accomplishments of the past. We also consider needs … Continue reading benefiting society


Bicycles were introduced in the 19th century in Europe and now number more than a billion worldwide, twice as many as automobiles. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for such uses as children’s toys, general fitness, military and police applications, courier services and bicycle racing. Design Behind the Bike – Series explores the effect of science and technology on cycling and explores how the development in technology has changed bike design and build over the last 100 years. Top 10 cycling innovations 2014 – … Continue reading bicycle

Beach Walker

Beach Walker (video 2:57) – Theo Jansen’s strutting sculptures achieve astonishingly lifelike movement at Art Basel on Miami Beach. “The walls between art and engineering exist only in our minds.” —Theo Jansen Theo Jansen is a Dutch artist. In 1990, he began what he is known for today: building large mechanisms out of PVC that are able to move on their own, known only as Strandbeest. His works are a fusion of art and engineering. PVC tubing – Since 1947 Dutch law has decreed that this strandbeest-yellow-tube be used to conduct electricity cables in houses. So it is very cheap. … Continue reading Beach Walker


Biodegradation is nature’s way of recycling wastes, or breaking down organic matter into nutrients that can be used by other organisms. “Degradation” means decay, and the “bio-” prefix means that the decay is carried out by a huge assortment of bacteria, fungi, insects, worms, and other organisms that eat dead material and recycle it into new forms. Biodegradable Products Institute – promote the use and recovery of compostable materials, science of biodegradation Bio-Wool in Terracase Suitcase – his starting point was that he wanted to find a way to utilize waste produced by New Zealand’s wool industry, one of the … Continue reading bio-degradable
