Abstract: A sensor for measuring ocean water salinity is described. The sensor may include a measurement clock circuit, a control clock circuit, and a comparator circuit. The measurement clock circuit, having an output that varies with salinity of a fluid, may have a first circuit architecture that includes a capacitive gap assembly that permits a fluid to flow into a gap between two electrodes of the capacitive gap assembly. The control clock circuit, having an output that does not vary with salinity of the fluid, may have a second circuit architecture comprising a capacitor. The comparator circuit may be configured to compare the controlled clock output to the measured clock output over a duration of time to determine a salinity measurement of the fluid. The first circuit architecture may differ from the second circuit architecture in that an electrically connected position of the capacitive gap assembly within the first circuit architecture is the electrically connected position of the capacitor within the second circuit architecture.

Abstract: A layered textile energy storage device can include first and second encasing layers, an anode, a cathode, and a flexible separator layer. The first and second encasing layers can each include a nylon fabric coated with a polyurethane. The anode can include a carbon fabric coated with anode active material, carbon nanotubes, and a binder material. The cathode can include a carbon fabric coated with cathode active material, carbon nanotubes, and a binder material. The flexible separator layer can be disposed between the anode and cathode to prevent internal shorting of the layered textile energy storage device. The anode, the cathode and the flexible separator layer can be disposed between the first and the second encasing layers.
