Also, for our artificial iris we are using liquid crystal technology, which can have a power consumption as low as 1 microWatt per square cm. Classic LCDs have a much higher power consumption mainly because of the backlight.
It seems that a much easier application would be to use a liquid lens and a distance sensor to produce a self focusing lens. The challenge, when driving, would be to avoid focusing on the automobile windshield and to focus on the road instead.
A logical step in technological evolution for me but my daughter pointed out the Scifi series Continuum where contact lenses are taken to another dimension. Thinking back to some older Scifi shows, they already implied the use of tablets, video phones and tricoders. Maybe we should take a closer look at what SciFi shows us now. This may be soon the next gadget of technology.
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.
