Ion Channels in Geopolymers- Artificial Synapses with Unique Electro-mechanical Properties
Abstract
Theoretical models will be developed to relate the electro-mechanical properties (i.e., memristance, piezoelectric charge factor, piezoelectric voltage factor, and piezoresistive gauge factor) to the geopolymers’ microstructure in terms of pore size, shape, and orientation, water content and mobility, ions type, geopolymers precursors, and manufacturing process. Multiphysics simulations will support the formulation of theoretical models and provide solutions for phenomena that cannot be mathematically solved, such as the Navier-Stokes equations describing the water laminar flow inside the geopolymers’ pores. Experimental tests at the nano-, micro-, and macro-scale involving depth-sensing indentation and more conventional electro-mechanical tests will validate the theoretical models.
