Scientists across the globe keep trying different permutations and combinations to come up with new inventions. There have been several inventions in the past that have helped us grow as a society and several of them are in the pipeline. Here is a look the latest inventions in science:

Three Dimensional Printing
You can draw in the air by using this unique pen invented by Peter Dilworth and Max Bogue. A colourful spool of plastic thread is inserted into this pen. The thread is extruded as heated plastic that cools down and solidifies as soon as it comes out of the tip. You can draw 3D structures on any surface or from any surface in the air using this pen called 3Doodler. It weighs around 7 ounces and is 7 inches long. Peter and Max have received several advanced orders for this pen.

Augmented-Reality Helmet
This helmet has especially been created for the cyclists. It gives them a 360 degree view of the road and has been designed to prevent accidents. The British product design firm DCA has invented this optic helmet with this unique headgear that features front and rear cameras. It is also equipped with a drop down visor that gives live-streaming from the rear camera to give the field view to the rider.

Sterilizing Spray
Invented at Turkey’s Saarbrücken Institute for New Materials, this is a breathable spray-on invisible thin glass coating. It has been devised to sterilize, strengthen and protect surfaces. It also repels bacteria, fungi, viruses, mildew, dirt, stains and water. This environmental friendly coating, patented by Nanopool GmbH Germany, is just about 100 nanometres thick which means it is 500 times thinner than the human hair. The coating can render any surface free from anti-microbes.

Bendable Battery
An all new bendable lithium-ion battery has been invented to power wearable devices. It can twist and flex and is being developed with the aim of creating a flexible smartphone. The battery which is still in its early stages of development has been tested to endure bends, twists and other kinds of deformations and yet charge.

Water Drop Lens
Inventor, Bruno Berge has come up with a liquid optical lens. With the help of a process called electro-wetting, a drop of water is settled on a metal substrate and is covered by a thin insulating layer. On applying voltage to the metal the angle of the liquid drop gets changed. The use of liquid lowers the cost construction. The lens has a large inverse focal length range, high optical quality, quick response and can operate in wide temperature range.
