    Abstract: Engineered cardiac tissue structures and methods for forming the engineered cardiac tissue structures are provided herein. An example engineered cardiac tissue structure includes a support having a first side and a first engineered cardiac tissue layer disposed at the first side of the support. The first engineered cardiac tissue layer can include a geometrically insulated cardiac tissue node. Another example engineered cardiac tissue structure includes a support, a first engineered cardiac tissue layer, and a second engineered cardiac tissue layer. Excitation and contraction of the first engineered cardiac tissue layer bends the support and strains the second engineered cardiac tissue layer inducing excitation and contraction of the second engineered cardiac tissue layer. The excitation and contraction of the second engineered cardiac tissue layer bends the support and strains the first engineered cardiac tissue layer inducing excitation and contraction of the first engineered cardiac tissue layer thereby producing antagonistic cyclic contractions.

    Abstract: Photosensitive cardiac rhythm modulation structures and systems are described. A genetically-engineered tissue comprising a population of pacing cells expressing a photosensitive membrane transport mechanism that is responsive to light of a particular wavelength(s) combined with one or more of a light source, a power generator, and a sensor provides pacemaker and/or defibrillator function to a subject. The systems further provide in vitro model systems for electrophysiological studies.
