  Based on a combination of insights afforded by Rainer Picard and Serge
Nicaise, we extend a set of abstract piezo-electromagnetic impedance boundary
conditions. We achieve this by accommodating for the influence of heat with the
inclusion of a new equation and additional boundary terms. We prove the
evolutionary well-posedness of a known thermo-piezo-electromagnetic system
under these boundary conditions. Evolutionary well-posedness here means unique
solvability as well as continuous and causal dependence on given data.
