Iddo Genuth writes "HP and Crospon have developed a skin patch employing microneedles that barely penetrate the skin. The microneedles can replace conventional injections and deliver drugs through the skin without causing any pain. The skin patch technology also enables delivery of several drugs by one patch and the control of dosage and of administration time for each drug. It has the potential to be safer and more efficient than injections."
