|The actuator to be able to demonstrate the artificial muscle (metallic ion exchange Polymer + electrode) and the sensor function by one material began to appear in the world and was developed. If the outside power is given to this actuator, the electromotive force of several mV is generated in proportion to displacement. Therefore, it functions as a load sensor, a displacement angle sensor of the bend etc and an acceleration sensor. Moreover, it is sensing with sensitivity sufficient from the very small power not more than 0.001N to the big power beyond 10N by adjusting the shape of the thickness etc. of the sensor (actuator). Moreover, because this artificial muscle is made of a flexible polymer, it can be facilitated to set it up according to the shape of the measuring object. It functions exactly similarly to man's finger because it has flexibility, high sensitivity and the actuator function.|
The warp can be measured only by cutting out a film sensor actuator to a suitable size, and pasting it to the measurement object. Because the sensor generates the electromotive force, an external power supply for sensing is unnecessary.
|Pressure distribution measurement|
The pressure distribution can be measured by dividing the electrode on the sensor surface according to the value of the electromotive force of each place. Even after making the sensor, the division of the electrode is freely possible.
It is a virtual hand that arranged the sensor cut out as five sensors. The electromotive force corresponding to the bend angle of the finger is generated.
The electromotive force wave form when the sensor is bent is displayed in the oscilloscope. The displacement of the sensor by the outside power and the electromotive force change according to the direction of the transformation can be observed.
|The outside power detection sensor|
The electromotive power at the time of external force joining an element is detected, and it is controlling so that an sensor moves in the opposite direction with external force.
|Contact detection actuator|
Even when the voltage is given from the outside for the sensor drive, the electromotive force by the outside power is generated. And, this can be detected. In left animation, to detect contact with the obstacle while driving the sensor, and to part from the obstacle, it controls.
|This sensor is compound single material and differs from the conventional device made combining the parts of each function greatly. Because the sensor is a single material, making the element of 1mm or less is also possible. Therefore, it is possible to miniaturize, to lighten, to be made to high performance, and to be expected the application by the robot, the medical treatment device, the information I/O device, home automation and the machine industry, etc.|
