One of the many advantages of Selective Area Laser Deposition (SALD) and Selective
Area Laser Deposition Vapor Infiltration (SALDVI) is that they can be used to embed in-situ
micro-sensors within macro-components. A single-point SiC/C thermocouple sensor embedded
within a SiC macro-component and electrically insulated with silicon nitride layers has been
demonstrated. In many applications, multi-point sensors within a single component are needed,
e.g., in monitoring the temperature gradient and distribution at different positions. In this paper,
multi-point thermocouple devices are demonstrated. The macro-component is a SiC bulk shape
made by infiltrating vapor deposited silicon carbide into a silicon carbide powder bed using the
SALDVI technique. Multiple SiC/C thermocouples are embedded in-situ in the SiC bulk shape
using the SALD technique. The transient and steady state responses ofthe embedded
thermocouples are compared to reference thermocouples probing the surfaces of the bulk shape.Mechanical Engineerin
