PURPOSE:To obtain a stable stress detecting element with good detection sensitivity, by using a material wherein charge transfer type complex formed of electron acceptors and electron donors is dispersed into a high polymer material. CONSTITUTION:Tetrathiatetracene (TTT) is dissolved into toluene heated at 70 deg.C till the saturation. When carbon tetrachloride is mixed with the same amount of the toluene and kept at 70 deg.C, the precipitate of TTT-CCl4 complex can be obtained. It is filtered, the precipitate is decomposed, this precipitate is added to the toluene solution of polystyrene so that the added complex may be in the same weight as the polystyrene, and it is sufficiently kneaded. After the mixed charge transfer complex is sufficiently dispersed, it is casted into a mold to obtain a plate-like product. This plate-like resistant material 1 is mounted to an outer frame 4 by evaporating electrode patterns to deposit on the upper and lower side thereof, and lead wires and led out and attached to an external frame. Si rubber 5 is adhered on the back of the material 1. When the surface is pressed, the plate is deformed, the resistance between electrodes is varied and functions as a pressure detection element. |
