Biomedical and Bioinspired Circuits and Systems
This research line embraces all activities related with the development of alternative bio-instrumentation circuits and systems required to reproduce classical and to propose new measurement techniques at bio-medical labs to improve the quality of acquired biosignals.
Targets design for bio-instrumentation systems are focused also to reduce the human effort and cost of biomedical assays, to obtain the minimum size and weight of biosystems (Lab-on-a-Chips, LoCs), to research new measurement methods based on high performance integrated circuits and system design with low-power consumption, wide bandwidth, reduced power supply levels and wireless communication capability. Electrical modeling of sensors required as signal transducers and interfaces must be incorporated to circuit design flow to obtain full system characterization. This research line also considers the modelling of heterogeneous systems for full system simulations.
