Bioimpedance refers to the passive impedance of biological tissues to an injected electrical signal. These impedance measurements are dependent on the structures and materials of the tissue and provide an avenue to detect physiological changes.
Our research focuses on creating the tools and signal processing methods to collect this information from biological tissues and exploring the applications of monitoring localized tissue changes resulting from fatigue and recovery.
Fractional Circuits and Systems
Fractional-order circuits and systems incorporate concepts from fractional calculus into electrical designs. These concepts increase the flexibility and control available when implementing a circuit design.
Our research focuses on developing the circuit theory required to design and implement analog filter circuits using fractional impedances. Realizing filters that provide flexibility not easily realizable with traditional circuits. Further, developing the signal processing methods needed to characterize materials with fractional-order impedances (supercapacitors, batteries, fuel cells) to further explore their underlying characteristics.
