Suman Chakraborty - syringe technology

Speak NowA needle as fine as a mosquito's proboscis now promises painless injection. Injections for people with injection phobia. Barely one - tenth the usual diameter, the needle can penetrate up to 3mm under the skin. And it hurts no more than a mosquito bite. 

Indian engineer Suman Chakraborty has developed this syringe with the help of a colleague from Japan. Its titanium needle can be used to draw blood samples. 

A micro - motor pumps a fluid into the hypodermic needle by stimulating the contracting motions of a mosquito's proboscis.

It can draw 5mm a second - enough for diabetics who need to monitor their blood sugar level.
