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.
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.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
