Abstract:
1. An implantable microstimulator device, comprising: a housing; a power source disposed within the housing; an electronic subassembly disposed within the housing and coupled to the power source; at least one electrode disposed on the housing and comprising a conductive base and polyoxometalate anions disposed on or within the conductive base, wherein the polyoxometalate anions comprise anions having the formula [X x M y Q w O z ] q− or the formula [X x M y Q w O z R r ] q− wherein M and Q are independently selected from Ta, V, Mo, Co, Cr, Ni, Nb, W, Ti, Fe, Ir, Ru, Zr, Mn, Zn, Pd, Sn, Pt, or Cu; X is selected from P, Si, B, Ge, As, or Sb; R is a covalently bonded substituent; x, y, w, z, and r are integers, wherein y and z are at least 5 and x, w, and r are at least 0; and q is an integer that represents the charge of the anion; and at least one conductor attached to the at least one electrode for conducting electrical energy to the at least one electrode from the electronic subassembly for stimulation of adjacent tissue when implanted.
