Have you taken a look at Kickstarter recently? Earlier this week, entrepreneurs were trying to fund more than 1,400 projects to build some kind of wearable device, and another 200 to build an IoT gadget.

Moving from an idea on Kickstarter to a prototype and then to mass manufacture is challenging, however. Many of these 1,600 developers have yet to find that out; other entrepreneurs have an idea but don’t have the time or cash to create a prototype they can display on Kickstarter.

Today, manufacturing a wearable requires either assembling components onto a printed circuit board—an approach that can be counterproductive when you are trying to make a gadget as small and light as possible—or developing a multichip module (MCM) or system-in-package (SIP), custom-built on an organic or ceramic substrate with copper wires connecting chips.
