It's only a matter of time before drugs are administered via patches with painless microneedles instead of unpleasant injections. But designers need to balance the need for flexible, comfortable-to-wear material with effective microneedle penetration of the skin. Swedish researchers say they may have cracked the problem.
In the recent volume of PLOS ONE, a research team from KTH Royal Institute of Technology in Stockholm reports a successful test of its microneedle patch, which combines stainless steel needles embedded in a soft polymer base – the first such combination believed to be scientifically studied. The soft material makes it comfortable to wear, while the stiff needles ensure reliable skin penetration.
Unlike epidermal patches, microneedles penetrate the upper layer of the skin, just enough to avoid touching the nerves. This enables delivery of drugs, extraction of physiological signals for fitness monitoring devices, extracting body fluids for real-time monitoring of glucose, pH level and other diagnostic markers, as well as skin treatments in cosmetics and bioelectric treatments.

I do believe that you are right. People who have gone through boot camp will never forget the "A shot". I can't remember what it was for, but we dropped our pants, and got stuck in the buttock. Shot was recieved early in the morning, then we did extensive calisthenics all day long, late into the evening. We were told quite bluntly that if you sat down and failed to exercise, that shot would all but cripple you for a week. Despite all the preventive measures, it was still hard as hell to get on your feet the next morning.
Don't quote me, but I think the shot contained a gallon and a half of genuine Navy Bull Shit.
