Abstract: The device has a base element and a switch element with auxiliary electrodes in the lateral direction. A voltage is applied to electrodes and the auxiliary electrodes to open switch contacts so the electrodes and auxiliary electrodes have first and second potentials, resulting in electrode and auxiliary electrode surface areas with positive and negative charge carriers in the lateral direction and equal charge carriers in the orthogonal direction. The device has a base element and a switch element with auxiliary electrodes (EG,ES) in the lateral direction to which a voltage can be applied. The voltage is applied to electrodes (HG,HS) and the auxiliary electrodes to open switch contacts so the electrodes have a first potential (U1) and the auxiliary electrodes a second potential (U2), resulting in surface areas on the electrodes and auxiliary electrodes with positive and negative charge carriers in the lateral direction and with equal charge carriers in the orthogonal direction. AN Independent claim is also included for the following: a portable terminal with an inventive device.

Abstract: The surface modification of polyimide materials by a chemical process is disclosed to provide a variety of functional groups on the surface. The surface is treated to produce polyamic acid carboxyl groups which are subsequently reacted with epoxies, hydrazines, or alcohols. The carboxyl groups can also be subjected to other organic reactions, such as reduction with metal hydrides and the like. The versatility and controllability of this process lends itself to promoting adhesion of the polyimide to similarly treated polyimides, other polymers and other substrates as well as combining with metals such as metal catalysts used for depositing conductors on non-conductive surfaces such as circuit boards.
