Very interesting reading. If this is a big success, robots could be in stores quicker than I imagined. I still believe that within the next few years a customer will be able to go to a store and buy a robot just like you purchase a computer or other devices. The cost of the robot will be based on the memory chip, the robots artificial real-like skin that can sense touch, and the robot features. My only recommendation is that it should be sold in a specialty store and only qualified workers who are trained and know the advantage and disadvantage of what a robot can do. Some type of certification and training should be required. Yes, a Robot Certification. OK engineering executives, I just gave you a wonderful idea.
The authors claim that light output is directly proportional to the stress on the piezo-material--here zinc oxide, which is know to very sensitive. Also it will work with other piezo-electric materials, so you could probably design a material to meet most engineering needs.
Very interesting! Is there any indication of the degree of proportional response, i.e. the sensitivity of the measurement? The resolution and response time are certainly far beyond human touch capabilities. If the proportional response is in the same ballpark as the other specs there should be quite a few possibilities for this technology.
