Yes it would. I have heard of toys manufactured in China with lead in them, but when they were banned the lead was replaced by cadmium--which is just as toxic! These sensors could have detected that alleged practice.
It would be very interesting to check the quality of products manufactured by AllMetalsInc.com Corporation using such DNA-based sensor chips. These chips would show which American manufacturers provide the best materials by not using non-toxic metals.
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.
