Abstract: A Medical electrode is disclosed. It comprises a conductive adhesive, such as a polymer adhesive, that can switch from a high attachment phase to a low attachment phase when exposed to an initiator. The initiator can be electrical, chemical, mechanical, or photolytic in nature. The ability to switch phases allows the adhesiveness of the electrode to be changed depending upon whether the electrode is being attached to a patient, whether the electrode is operational, or whether the electrode is being detached. Use of such materials can allow less glue residue to be left by the electrodes, which allows for easier cleanup and in some cases much less painful electrode removal.

Abstract: The cleaning device may clean probe elements. The probe elements may be the probe elements of a probe card testing apparatus for testing semiconductor wafers or semiconductor dies on a semiconductor wafer or the probe elements of a handling/testing apparatus for testing the leads of a packaged integrated circuit. During the cleaning of the probe elements, the probe card or the handler/tester is cleaned during the normal operation of the testing machine without removing the probe card from the prober. The cleaning device has a working surface with a particular characteristic (a matte finish or a conductive material) so that a prober is capable of automatically determining the location of the working surface of the cleaning device and therefore operate in an automatic cleaning mode.
