Meaning

• Sensors are vital for intelligent processing.
• All focus areas are subject to monitoring needs,
  often with competing requirements for time
  response or location of sensors. Sensors play a
  critical role in the development and
  implementation of advanced and new unit
  processes.
• Today many sensors are selected for use in unit
  processes on the basis of their reliability and
  low cost, not because they measure parameters
  that are fundamental to the material being
  processed.

Importance

• Sensors are vital for intelligent processing. The
  requirement for improved sensor systems for
  process monitoring and control will become
  increasingly important as more-complex processes
  are developed for small-quantity production of
  precise and expensive components made of advanced
  materials.
• Because research on process modeling and material
  characterization cannot remove all uncertainty in
  the manufacturability of advanced work pieces,
  sensors will always be necessary for successful
  production.
• The adoption of sensor technology can make viable
  those unit processes that are inherently so
  complex or unstable that they demand continuous
  monitoring and control to ensure acceptable
  yields.

Key aspects of sensor technology to be emphasized
for RD include

• Sensor systems with digital architectures readily
  integratable with machine controllers
• intelligent sensor systems that employ advanced
  sensor fusion and feature extraction techniques
  for reliable process-state determination and
  diagnostic decision making
• process-specific sensor developments that address
  the need to monitor aspects of all five process
  components
• new sensor materials and techniques capable of
  monitoring nontraditional processes and the
  processing of nontraditional materials
• exploitation of sensor technology that was
  developed for applications other than unit
  manufacturing processes
