The early detection of minute cancer is very important, but that is difficult when using X-ray, ultrasonic, or an endoscope because of the small size and the disturbance by mucus. However that is said to be easy with direct palpation if possible. Then the paper proposes a new hardness sensor for cancer palpation, which is inserted into a human body with an endoscope, presses the object surface uniformly by a balloon through elastic beams, and detects the hard part based on the deflection of the beams. The sensor features : 1)no-damaging property with its flexibility, 2)independence from the existence of mucus and the object shape, and 3)simple structure, etc. The paper also introduces the conductive rubber for plural strain gauges. The results of measuring experiments with the constructed sensor showed the availability in a straight and an uneven pipes and the possibility of 2-dimensional measurement.
