Researchers at Ga Tech have developed inks that you can put into your conventional inkjet printer and create conductive traces. Your PCB can be made of paper if you like. Here's the link: GA Tech Develops Inkjet-based Circuits
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
