It looks very promising if they can scale to smaller and larger scale lengths. Another thing is the natural dispersion of distances. But it is definitely the cheapest sub-20 nm method I've seen so far.
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.
