We have all suffered from pains of injection in different ways, but it is about to become more encouraging that you would head to the clinic to have lovely injection! Mimicing how mosquitos suck blood(only females bite, I mean moquitos!), providing microelectromechanical pump!, some people from India and Japan, have created microneedle, for easy, painless injections. It's got the size of 25 microns* (inner diameter) and 60 microns(outer diameter) as big as mosquito's mouth! It is made of strong Titanium. I wish it had been designed in my childhood! more we get closer to natural practical solutions of nature, more we get powerful.
* 1 micron= 0.001 mm
