“Embedded Sensing”

 

Abstract: 

Traditional embedded sensing processes, consist of placing sensors on the surface or within prefabricated cavities of components. However, these methods can be intrusive in nature or interfere with the proper fit up of nested mechanical parts, resulting in non-optimal mechanical and thermal performance responses. As a result, instrumented mechanical assemblies have often demonstrated limited capabilities for gathering system response and survivability data during normal and abnormal environmental conditions. Recently, E-1 has focused on developing techniques for producing high fidelity mechanical components with embedded sensing capabilities that do not affect the performance of the assembly. Embedded sensing can be a pathway for obtaining non-intrusive real-time performance response feedback during in-situ monitoring operations. Thus, there is a critical need for developing techniques for embedding sensors and electronics within mechanical components in metals, polymers, ceramics, and composites. More recent studies focus on the development of conformal additively manufactured sensors.

Bio:

Cesar Dominguez’s research focuses on developing methods and techniques for embedding custom and commercial off-the-shelf sensor packages and data acquisition (DAQ) systems within components and/or mechanical assemblies. Currently, he is a research and development (R&D) engineer within the Mechanical & Thermal Engineering (E-1) group at the Los Alamos National Laboratory (LANL) where he serves as the subject matter expert (SME) on embedded sensing. Previously, he was an NNSA Graduate Fellow and graduate researcher at the W.M. Keck Center for 3D Innovation at the University of Texas at El Paso where he obtained his masters and bachelors in Mechanical Engineering with a focus on Additive Manufacturing
