Project Description:
Sensors or sensing systems are increasingly critical in a variety of
applications including national security, surveillance monitoring and health
care. Those systems should function with minimal hardware recourses, minimal
communications and minimal computation overhead, and these efficiencies can
dramatically improve the performance, reliability and usability, which can
broaden the overall application scope of sensor systems. This project is
to pursue preliminary results of dynamic configurability of architectural and
circuit models in sensing systems, and the proposed research will have
significant impacts on a range of sensing applications under the
resource-constrained environment. For example, in large-scale sensor networks or
implantable sensors, energy is tightly constrained. The ultimate goal of the
research is to exploit the configurability and dynamics of sensing systems to
improve the overall system efficiency. This project serves as an expedition to
investigate the dynamically architectural sensing techniques and may open a new
research direction of theory and practice in the signal acquisition. Upon the
success of this project, a better performance-energy tradeoff in the sensing
system will be obtained, which can further strengthen its advantage compared to
other sampling techniques, and extend its application regime.
