“Micromachine for Diagnostics”
SBIR Background
Small Business Innovation Research
Sponsored by National Automotive Center in
TARDEC

Program Vision
TARDEC expressed interest in a “MEMS
chip” that can be targeted to multiple
diagnostic and prognostic applications on the
vehicle and produced in high volumes
MEMS = Micro ElectroMechanical Systems
ASTI added wireless digital
communications as a critical
element of an embedded
diagnostics architecture

An Embedded Diagnostics and
Prognostics Architecture
Why an “architecture”?
Everything essential has its place
Elements are arranged to work well
together
Design can be altered to fit
client/customer’s needs
Provisions for future
additions

Challenges to an Embedded
Diagnostics and Prognostics
Premise: dedicated sensors will improve diagnostic and
prognostic capability.
How to integrate more and more sensors (MEMS and
conventional) at reasonable cost and complexity?
 Wireless communication inside the vehicle
(AKA “cable replacement”)
How to effectively present diagnostic and prognostic alerts to
vehicle operators?
 Vehicle bus integration, graphical displays
How to efficiently communicate diagnostic
and prognostic results to maintainers and
the logistics community?
 Vehicle bus integration
 Wireless communication outside
the vehicle (e.g. Bluetooth)

SBIR Program Phases
Phase I: Conceptual design & feasibility
study
Phase II: Detailed design, simulation,
prototype fabrication, laboratory evaluation
Phase II-Plus: Demonstrate additional
diagnostic and prognostic
applications, prepare for
pilot production
