    摘要： A strain sensor resistor includes: a resistive element (thin-film strain-resistive layer) formed nearly at the center of an upper surface of an insulation substrate to be a base; and front surface electrodes layered and formed on either end part of the resistive element and electrically connected to the resistive element. The entire upper part of the resistive element and a part of the front surface electrodes are covered by a protective film (protective coating). Moreover, back surface electrodes electrically connected to the front surface electrodes are formed on either lower end part of the insulation substrate, and end surface electrodes are formed on either longitudinal end surface of the insulation substrate. The strain sensor resistor has a tip shape solder mountable on a circuit board etc. using the back surface electrodes.

    摘要： A method of manufacture of a strain gage or flexible polyimide-based resistor, the method including the steps of providing a flexible polyimide substrate, joining a conductive foil to the flexible polyimide substrate, applying a layer of photoresist to the conductive foil and thereafter, patterning the conductive foil by etching using the photoresist, wherein the method is characterized in that it includes at least one of the following steps: surface conditioning of the flexible polyimide substrate using mechanical abrasion, scrubbing of the conductive foil prior to the patterning, removal of photoresist by scrubbing following the patterning, pressurized cleaning, using deionized water, following the patterning, automated algorithmic resistance calibration and shunt trimming and forming an emulsion layer of epoxy over the conductive foil following the patterning.

    摘要： A force sensitive resistor includes first and second electrical contacts, and a layer of deformable material impregnated with carbon nanotubes. The layer of deformable material is arranged between the first and second electrical contacts. A difference in the conductivity of the impregnated material caused by deformation of the material is detectable across the contacts. A method of manufacturing a force sensitive resistor includes the steps of providing first and second electrical contacts, and arranging a deformable material impregnated with carbon nanotubes between the first and second electrical contacts. Again, a difference in the conductivity of the impregnated material caused by deformation of the material is detectable across the contacts.
