Overcoming Fear of Needles
I don’t think this exists, but came across Pinsoft, a speculative design from university students in Spain as a possible solution for people that have a fear of needles.
According to the creators, Pinsoft works because:
[It] stimulates the area near the puncture. It works thanks to rounded-tip spikes, which contract thanks to springs, adapting to the patient's surface. As the needle is inserted, they put pressure on the proximal area and there is a feeling of relief from the prick.
In other words, the prongs distract you from the actual needle.
