What do this satellite thruster, plastic tool, and micro mechanical switch have in common? Well they all contain components that bend, so-called compliant mechanisms This episode was sponsored by SimpliSafe. More about them at the end of the show. Now about a month ago I was giving a talk in Utah hence the suit and that's where I met this guy, -Lar... Read More
