We often write about the race to shrink transistors to very smaller dimensions with a view to the PC industry – as that is a major focus of HEXUS. However, it is sometimes interesting to take a sideways glance at what other advances these miniature modern marvels can enable. A blog post by Columbia University on Wednesday provides some insight into using the latest TSMC made chips in med-tech devices. As you can see from our main picture these chipmaking advancements have enabled "the world's smallest single-chip system," which is tiny enough to fit in the tip of a hypodermic needle.
