Electrical impedance tomography through constrained sequential linear programming: a topology optimization approach

Autor: Luis Augusto Motta Mello, Cícero R. de Lima, Raul Gonzalez Lima, Emílio Carlos Nelli Silva

Publikováno v: Measurement Science and Technology. 18:2847-2858

Electrical impedance tomography (EIT) is an imaging method that estimates conductivity distribution inside a body. In EIT, images are obtained by applying a sequence of low intensity electrical currents through electrodes attached to the body. Althou

On the optimization of piezoresistive plate-based sensors with distribution of piezoresistive material

Autor: Luis Augusto Motta Mello, Emílio Carlos Nelli Silva

Publikováno v: SPIE Proceedings.

Piezoresistive sensors, which have been widely studied and applied to several applications, are usually made of a piezoresistive membrane attached to a flexible substrate, a plate. A topology optimization formulation for the design of piezoresistive
