ABSTRACT
Abstract??This paper presents some ideas for the membrane thickness design of of implantable bio-micro-electro-mechanical systems (bio-MEMS) for thein situmonitoring of blood flow. The objective is to develop a smart wireless sensing unit for non-invasive early stenosis detection in heart bypass grafts. The design includes considerations of nonlinear material models, multiscale blood flows, and appropriate analyical models for data interpretation, as well as preliminary studies of the pressure and flow sensing concepts. The paper also examines the use of surface coatings for the design on biocompatibility and non-adhesion of blood platelets and constituents. The implications of the results are discussed forin vivodeployment of such sensor systems.
