Electric component of small overall size and low weight, the characteristic value of which is variable in that it is carried by a deformable substratum; the component is in conductivity relation with other elements through deformable conductors and terminals; the component may be an elementary one such as resistance, capacitor, solenoid, photo-sensitive material and leads to complete circuits such as switches, rectifiers, pression-detectors, microphones and the like, while said conductors and terminals may namely be used in the tension feeding of artificial pacemakers.
