Pressure sensitive conductor and method of manufacturing the same

In a method for the manufacture of a pressure sensitive conductor comprising an insulating elastomer having dispersed therein from about 3% to 40% by volume based on the total volume of electrically conductive magnetic particles having a particle size of from 0.01 .mu.m to 200 .mu.m, the said particles being concentrated and distributed in portions of the conductor in accordance with a selected pattern in which those portions having a relatively high concentration of particles are high sensitivity conductor portions and other portions are insulator portions;

• the improvement comprising first forming a mixture containing said elastomer and said particles, forming said mixture into a sheet having a viscosity of from 10.sup.4 to 10.sup.7 poises at a strain rate of 10.sup.-1 sec..sup.-1 , subjecting said sheet to the action of shaped magnets forming a magnetic field of a selected pattern, and thereafter curing said elastomer.
