Title:
ACTIVITY FORCE SENSOR FOR HEART PACEMAKER
Document Type and Number:
Japanese Patent JPS6395074
Kind Code:
A
Abstract:
In order to avoid depolarisation in an activity sensor in which a piezoelectric device of the flexural type is used, even with high mechanical loads, and to simplify contacting of such a sensor regardless of the surface it is mounted on, the invention provides that the piezoelectric device consists of two adjacently situated, separate or continuous piezoceramic parts (16, 17) which are polarised in opposite senses and are provided with electrodes (18-21) on both sides. On one side, the electrodes (18-21) are electrically connected to each other and on the other side they are connected to terminals.
