Presentation Transcript

  1. MicroLabs Automated Chemical and Biological Sensing in Sensor Networks

  2. Environmental Monitoring: A Living Laboratory in Cal-IT2 • Santa Margarita Ecological Reserve, SMER • 4,334 acre field station 50 miles NE of San Diego • Variety of habitat, terrain • A testbed for 56 ongoing experiments including sensing • Hydrology (stream flow, temp, pH, O2, conductivity..) • Microclimate, fire hazard • Chemical, biological agents • High Performance Wireless Research and Education Network • 45 Mbps wireless backbone running across southern CA connecting • SMER, Mt. Palomar, IGPP/SIO seismic network • Specific focus on real-time environmental monitoring • Seismic, oceanographic, hydrological, ecological data • http://hpwren.ucsd.edu

  3. Santa Margarita Ecological Reserve Water Chemistry Quality Stations Source, Dan Cayan, UCSD SIO

  4. Project Goal: computation+networking+sensing • BioChem Embedded and Networked Sensing (BCENS) nodes and nets • In-package integration of microfluidic, communications, networking and processing subsystems • Remotely operated, reconfigurable laboratories for biochemical analysis • Sub-systems • Biofluidic sample preparation, transport, disposal • Chemical analysis, biological assays • In-situ monitoring, control, communication, adaptation • Targeted for: crisis detection, evolutionary monitoring, genotyping

  5. In Simpler Terms

  6. In-package BioChemical Processing

  7. Subsystem: Chemistry Laboratory • Critical Actions • Sampling, Transport, Reagent Mixing, Packaging • Enormously challenging • due to surface chemistry (e.g., avoiding protein absorption), flow control (very low Reynold’s number), clogging/bubbling • Opportunities as well • DNA extraction from flow control, thermal management through flow control (rather than heat sinks) • Components • AC-pulsed MHD micropumps, microswitches • Polymeric microvalves, microtitration • Capillary electrophoresis for separation methods

  8. MHD Microfluidics

  9. Microfluidic Platforms • IC-like microfluidic processors for handling complex biofluids & self-calibration (BioFlips) • Micropumps, flow sensors, viscosity sensors, diffusion assayes, laminar flow-based target extractors, flow cytometers.
