Inspired by the bite of mosquitoes to get rid of mates pain

Engineers managed to make a microscopic needle inspired by mosquito bites that is painless. Hindi and Japanese engineers have designed a "micro-needles" that is mimics by a way that female mosquito uses for the blood-sucking, and when goes into the skin does not cause to any pain. Contrary to popular belief, the victim does not harm of mosquitoes, but also insect's anticoagulant saliva cause to pain that enters to the body to prevent of blood clots and inflammation. This new bio micro needle is designed by Suman Chaker Aborty, a researcher at Indian Institute of Technology in Kharagpour and Kazuyoshi Sitochia, a researcher at Tokai University in Japan. The female mosquito sucks the blood by stunning and relaxing a certain muscles. In this way a suction system is created, which causes to flow of blood into the insect's mouth. In this new needle sucking operation is performed by a micro electromechanical pump. Inner diameter new needle is of around 25 microns and its external diameter is 60 microns, which is about the same size mosquito's mouth that plays a role in this action. Needle size and performance system by sucking will not have pain. External diameter of normal needles of syringe is about 900 microns. According to ISNA, unlike the older micro-needles that are made of silicon dioxide, this new micro is made of less titanium alloys. In this way, the risk of breaking the needle during injection significantly is reduced. The needle is also strong enough to penetrate to a depth of three millimeters into skin and reach to blood vessel walls and can extract 5 ml of blood out in per second. This amount is enough to measure the blood's sugar levels in diabetics by using a glucose sensor that can be fitted on the needle.
