No more painful injections.

  • IIT Kharagpur along with Tokai University of Japan invents micro needles that can inject the drugs or extract blood painlessly.
  • The micro needle is developed on the basis of the principle of suction based pressure.
  • Diabetic patients will immensely benefit as they need to undergo pathological examinations very often for diagnosis and management.
  • The suction action is provided by the micromechanical pump which works using a piezoelectric actuator attached to the needle.
  • The diametre of the needle is as small as 30 micrometre. The device is also attached with a vibrator which helps in making the process painless.
