<p>The present invention relates to a method for manufacturing a piezoresistive sensor based on a cement matrix where a carbon nanomaterial is dispersed, which can obtain excellent resistance variation rate appropriate as a piezoresistive sensor by improving dispersion of a carbon nanotube in the cement sharply using sonication. The method for manufacturing a piezoresistive sensor based on the cement matrix according to the present invention includes: a step (S1) of mixing the carbon nanomaterial and a dispersing agent into water; a step (S2) of dispersing the carbon nanomaterial by performing sonication of an aqueous solution of the carbon nanomaterial and the dispersing agent; a step (S3) of manufacturing a cement matrix by mixing the aqueous solution of the carbon nanomaterial and the dispersing agent into cement; and a step (S4) of stirring the cement matrix.</p> |
