Japanese Researchers Develop Sensor Skin 106

Posted by ScuttleMonkey from the right-touch dept.
ScentCone writes "A University of Tokyo team has developed a flexible, laminated network of pressure and temperature sensors suitable for jobs such as robot fingers. Circuits as pressure sensors, and semiconductors as temperature sensors are not new, but the thin, networked laminate of the two is novel."

    Robots so far haven't been the best looking things, as their inventors rarely see a need to cover them up with "skin" or something that looks vaguely aesthetic.

    So maybe this will make new robots resemble something a bit more organic, by, say, colouring this stuff to look like human skin. I think this would go a long way in making them more appealing to the public.

      Its not just about making them more "appealing" to the public.

      This new "fabric" laminates the pressure and temperature sensing network together, so that both properties can be detected simultaneously, using carbon based circuits and semi-conductors, which is inexpensive to reproduce

      This would allow the scientists to measure more easily (if not more accurately), the effects a certain task would have were it performed by a human, the side effects certain working conditions may have (kind of prevention before cure), and in future they could add more sensors on these layers to measure other aspects (for example, radioactivity)..
    • making a robot look more human still doesnt make it look completely human. especially since itll probaly only look human enough to be creepy. kinda like the computer rendered movies like Final Fantasy... sure it looks real-ish... but the characters are still somewhat lifeless.

      Ah, but would you restrict the sensors to just fingers/hands/feet, or go for the whole 'body' ?

      To be useful, covering the whole body would require millions of sensors, and somewhat impractical to implement and process.

      I agree with earlier poster, the best use for this, is in prosthetics. We already have artificial limbs that can be 'moved' via crude nerve interfaces, add this on and the limb becomes a lot more useful. Much more usful than a Honda-bot that can pick up an egg without breaking it.

        Actually I think there might be a way to handle so many sensors.
            for every few hundred or so have a very simple processor that just looks for sensors that need attention (nearing temp/pressure boundries, changing enough to warrent attention, ect.) then when something happens it sends a simple message upstream to a more important processor (HEY sensor #252 is getting hot fast!) that processor then converts the info from it's subs into more general info for the main system and passes it on (LEFT HAND MELTING!). Of course the higher processors should be able to set alert criterion for lower processors and even query for specifics, but outside of the main system focusing it's attention it mostly just processes simple all o.k. messages from a small handfull of surface sensor agregators.
            I know I'm rarely aware of more than a general sense of to what degree I'm comfortable unless I specifically focus such as when testing the water temp in the shower or when accidently stub a toe.

        • Wouldn't a better way to avoid damage be to allow the processors closest to the sensor to quickly evaluate if it was being damaged and if so pull back the hand or whatever part without direct control from the main system? Sort of like when you're getting burned and you pull back before you even realize you were burned.
          • The human body already does something like this. If you touch a really hot object (say red hot metal) the way past limit signal hits the spinal cord and sets off a the pull-back reflex signal to the muscles even as the signal is being sent to the brain.

Simultaneous changes amongst several sensors should be sent to higher levels, those with highest magnitude of change or threatening acceptable thresholds given highest priority. Above threshold signals could be fast-tracked to a release actuator's processor like a pain reflex, which could then make the decision to "bear with the pain" or "let go", depending on how important the burde
