Generating main body 12 is fixed on the external membrane of heart of myocardial wall by the fixed cell 13 on angular three summits.And the three of generating main body 12
Each angular side is not fixed, contraction and diastole so both without limitation on heart, additionally aids piezoelectric material layer with the heart
Dirty motion deforms upon to produce electric energy.
The advantage that generating main body 12 makes triangularity is that can more gather the energy of heartbeat, because
The not only contraction and diastole of transverse direction, also has longitudinal contraction and diastole, when using triangle during heartbeat
During shape, a summit of triangle is set to the direction towards the apex of the heart, and two other summit is set to laterally receive with heart
The direction of contracting is parallel, and so whether heart cross-direction shrinkage is longitudinal contraction, can drive generating main body 12 to deform.Therefore
The shape of triangle can more utilize the energy of heartbeat generation than the shape of quadrangle.
Fixed cell 13 is extended by encapsulated layer and formed in corresponding position, and the inside of fixed cell 13 does not contain piezoresistive material
Material and electrode material, therefore damage piezoelectric material layer and electrode layer in suture can be avoided.
