These researchers claim to be able to fabricate simple sensors and similar circuits that can be directly attached to the objects being monitored. The inexpensive process should enable them to be used for all sorts of interesting applications, such as monitoring food spoilage.
Lots of applications exist for very simple and targeted sensors capable of adhering to any shape or object. Assuming the circuit performance is stable and repeatable in bulk then adding simple memory to it (for read back later), or perhaps a simple RF or NFC link would be all that you need to get commercially viable (and very cheap) sensor systems.
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
