Welcome to the world of inexpensive sensors for clinics, offices and homes
A new simple tool developed by nanoengineers at the University of California, San Diego, has opening up a wide range of possibilities for people to build and use sensors, Imagine ballpoint pens filled with high-tech bio-inks that can be used to detect glucose levels in diabetics, measure pollution on leaves or could be used on the battlefield to detect explosives and nerve agents.
Engineers have developed a new simple tool that can help you build a sensor anywhere.
The invention may open a new window to the world of inexpensive sensors for personalised used at clinics, offices and homes.
The team from the University of California, San Diego, developed high-tech bio-inks that react with several chemicals, including glucose.
They filled ballpoint pens with the inks and were able to draw sensors to measure glucose directly on the skin and sensors to measure pollution on leaves.
“Our new biocatalytic pen technology, based on novel enzymatic inks, holds considerable promise for a broad range of applications on site and in the field,” said Joseph Wang, who led the research team.
Sensors can also be drawn directly on smartphones for personalised health monitoring or on external building walls for monitoring of toxic gas pollutants, researchers said.
The sensors also could be used on the battlefield to detect explosives and nerve agents.
Researchers estimate that one pen contains enough ink to draw the equivalent of 500 high-fidelity glucose sensor strips.
The engineers also demonstrated that the sensors could be drawn directly on the skin and that they could communicate with a bluetooth-enabled electronic device to gather data.
The pens would also allow users to draw sensors that detect pollutants and potentially harmful chemicals sensors on the spot.
The findings were published in Advanced Healthcare Materials.(IANS)
8 ft 1 tall Sultan Kösen from Turkey is a rare specimen – the tallest over 8 ft tall man alive on planet Earth today according to the Guinness World Records.
Sultan currently also holds the record for largest hands 28.5 cm (11.22 in) from the wrist to the tip of the middle finger and the second largest feet – his left foot measuring 36.5 cm (1 ft 2 in) and right foot measuring 35.5 cm (1 ft 1.98 in).
Guinness World Records has come across only about ten people above 8 ft over the past 20 years but Sultan is the only such person alive today.
Born on 10 December 1982, Sultan was like an average child till the age of 10, even the other members of his family, including his parents and four siblings were ‘normal’ in terms of size.
But suddenly Sultan started growing uncontrollably fast due to a condition called “pituitary gigantism” which accounts for over-production of growth hormone and its spread from the pituitary gland in the brain. This invariably leads to large hands, thickening of the bones and painful joints. Due to his extreme size, Sultan had to face many ups and downs in life. Because of his gigantic height Sultan couldn’t finish school, could never find fitting clothes or shoes and found it extremely hard to fit into a regular-size car.
On the other hand because of his height he was found to be good at changing bulbs or hanging curtains.
Sultan Kösen today is recognized everywhere around the globe because of his extraordinary height and invited to star in a number of Hollywood movies.
