The invention provides an ultra-soft high-
conductivity flexible
electrode patch and a preparation method and application thereof, the flexible
electrode patch comprises the following components: a single-
ion conductive storage battery
brush polyelectrolyte monomer, movable ions, an alkaline
solvent, a cross-linking agent and a
photoinitiator, one
end group of the single-
ion conductive storage battery
brush polyelectrolyte monomer is carboxyl, and the other
end group of the single-
ion conductive storage battery
brush polyelectrolyte monomer is hydroxyl. One
end group is a carbon-carbon
double bond, the other end group is a carbon-carbon
double bond, the single-ion conductive storage battery brush polyelectrolyte monomer further comprises at least one polar group, and the preparation method of the flexible
electrode patch comprises the following steps: dropwise adding a flexible electrode precursor solution on the surface of a tissue in situ, and rapidly curing and forming under the
irradiation of
ultraviolet light to form an ultra-soft electrode adaptive to the shape of the surface of the tissue. The flexible electrode patch provided by the invention has the characteristics of extremely
low modulus, low ion and water molecule
leakage rate,
high conductivity and the like, and can form a
hydrogen bond with a
tissue surface to realize high
adhesive force. The flexible electrode patch is simple in preparation process, convenient to use and operate and beneficial to large-scale production and clinical application.
