Soft, flexible conductivity sensors for ocean salinity monitoring

Abstract

Flexible electrochemical sensors that measure the concentrations of specific analytes (e.g., ions, molecules, and microorganisms) provide valuable information for medical diagnosis, personal health care, and environmental monitoring. However, the conductive...

Soft, flexible pressure sensors for pressure monitoring under large hydrostatic pressure and harsh ocean environments

“…32 To further expand the potential applications of flexible electronics to a deep ocean environment, the desired sensors are expected to have robust performance over a wide range of hydrostatic pressures (e.g., on the order of a few or tens of MPa). 33,34 For example, in our previous studies, 33,34 we introduced soft, pressure-tolerant temperature and salinity sensors with high flexibility for operating under a large hydrostatic pressure (0.1-15 MPa) and high salinity (30-40 Practical Salinity Unit (PSU)) environments, thus eliminating the need for protection from pressure chambers and potentially achieving small sensor size and low power consumption.…”
