Towards Chip-Based Salinity Measurements for Small Submersibles and Biologgers

Figure 1

Schematic top view of a design containing (a) a temperature sensor, (b) three relatively small electrodes for pH and Cl⁻ concentration, (c) conductivity electrodes, and (d) a strain gauge for the pressure membrane sensor. The design is 7.5 × 3.5 mm in size.
