Compact Electrochemical Sensor Cells (280)

Problem: Need compact, adaptable electrochemical cell design for use in practical, portable sensors

Graphic of electrochemical cell design for protable sensors

Project Activity Scope (from Technical Overview Chart): Sensors and Devices through Integrated Systems

PNNL Solution:

  • Design cell with small dead-volume and variable flow volumes that allows sample size to be varied over wide ranges
  • Incorporate high surface area, chemically specific sorbent material into working electrode
  • Sorbent can be tailored for different target analytes

Capabilities Employed to Meet Client Needs: Component design; adaptation of commercial components (when available) to meet system requirements; material selection for compatibility with sensor requirements and fabrication processes; microfabrication with laser machining; subsystem assembly and evaluation; system integration and testing.
