HP Skin Patch May Replace Needles 190

Posted by kdawson from the you-may-feel-a-slight-pinch dept.
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."

        It's a good joke but the truth is that the last thing a woman wants is for a rapist with a hard-on to become a rapist with a butchered cock. He'd kill her at that point. It's better to knock the guy out and get away rather than risk leaving him maimed and enraged. Once he's knocked out, of course, his victim would be free to do as she pleases with his junk. I'm thinking something like a spring-loaded bear trap but scaled down to work on the winky.

    I foresee scores of people walking around with the HP logo tattooed where the patch was. Later the advertising space will be sold to other companies.
