Abstract
Ultrasound devices including wearable, patch-type ultrasound devices, which feature a porous graphene electrode prepared by graphitization of a polyimide precursor.
Claims20
An ultrasound device comprising:
- a) a first electrode comprising porous graphene, the first electrode being disposed within or on at least a portion of a substrate comprising a polyimide which has at least one aromatic ring;
- and
- b) a piezoelectric material disposed on the first electrode and within at least a portion of the porous graphene.
A method of making a device comprising:
- a) graphitizing at least a portion of a substrate comprising a polyimide having at least one aromatic ring to form a first electrode comprising porous graphene disposed within or on the substrate;
- and
- b) applying a piezoelectric material to at least a portion of the first electrode.
A method of assessing an anatomical structure in a subject, comprising obtaining at least one ultrasound image from an ultrasound device applied to a target area of the subject, wherein the ultrasound device comprises:
- a) a first electrode comprising porous graphene, the first electrode being disposed within or on at least a portion of a substrate comprising a polyimide which has at least one aromatic ring;
- and
- b) a piezoelectric material disposed on the first electrode and within at least a portion of the porous graphene.
