AKTIVITAETSSENSOR FUER EINEN HERZSCHRITTMACHER.

摘要

The activity sensor uses a pair of piezoceramic discs (16,17) polarised in opposition to one another with electrodes (18...21) a-plied to their opposing surfaces. The electrodes (19,21) on one side of the two adjacent discs (16,17) are coupled together, the remaining two electrodes (18,20) respectively coupled to positive and negative terminals (22,23). Alternatively, the two piezoelements are provided by a single plate with two electrodes applied to each of its opposing surfaces. The electrodes on one side of the plate are separated from one another by an insulating trough.
