Abstract:
An electric cooking appliance includes a glass-ceramic substrate having a top surface for supporting cookware for heating thereon, and a bottom surface opposite the top surface. The electric cooking appliance includes a plurality of thermoresistive heating elements disposed and spaced apart on the bottom surface of the glass-ceramic substrate, with each of the plurality of thermoresistive heating elements including graphene nanoparticles embedded in a ceramic matrix for generating heat upon application of electric current to the respective thermoresistive heating element. Each thermoresistive heating element is electrically connected to a power supply such that one or more of the plurality of thermoresistive heating elements are selectively activated to receive electric current to heat localized areas of the glass-ceramic substrate.
