A wearable sensor system includes a flexible patch, an electronic circuit disposed on the flexible patch, and a disposable sensor disposed on the flexible patch and connected to the electronic circuit via a socket. The disposable sensor detects a chemical compound. The electronic circuit generates a detection signal commensurate with the chemical compound detected by the disposable sensor. The disposable sensor is removably plugged into the socket, thereby permitting replacement of the disposable sensor upon satisfaction of a predetermined condition. A battery disposed is on the flexible patch and connected to the electronic circuit to power the electronic circuit. A transceiver is connected to the electronic circuit, wherein the transceiver transmits the detection signal.

A cyclone includes a hollow cylindrical upper portion and a hollow conical lower portion having an inclined wall and a base wall. The base wall and the inclined wall are continuous contact with each other, and the inclined wall of the hollow conical lower portion is in continuous contact with an outer wall of the hollow cylindrical upper portion. A total cyclone height is from about 10 to about 30 millimeters, and a ratio of the total cyclone height to an inner diameter of the hollow cylindrical upper portion is from about 0.7 to about 1.3. An angle between an inner surface of the base wall and an inner surface of the inclined wall is from about 110 to about 130 degrees.

Cyclone and methods of manufacture thereof

An anti-fouling coating comprising a polymeric compound, wherein a backbone of the polymeric compound is covalently bonded to a quorum sensing inhibitor, and wherein the anti-fouling coating has substantially no bactericidal activity, the quorum sensing inhibitor is substantially non-leaching from the anti-fouling coating, or both.
