摘要： A method for determining a health indicator parameter of a fluid are described. The method can include contacting at least one first functionalized electrode included in a plurality of functionalized electrodes of a sensing unit with a fluid. The method can also include generating a first electrical signal within the fluid by the at least one first functionalized electrode. The method can further include receiving, by at least one second functionalized electrode included in the plurality of functionalized electrodes of the sensing unit, a second electrical signal in response to the first electrical signal. The sensing unit can determine a health indicator parameter of the fluid based on the second electrical signal. The health indicator parameter can be associated with an electrochemical response signal included in the second electrical signal. The sensing unit can provide the health indicator parameter to a computing device communicably coupled to the sensing unit.

摘要： The present invention relates to an improved technology for a device that identifies and diagnoses an environmental stress state of plants. An environmental stress diagnosis device comprises a measurement light source 12, an induction light source 14, and a transmitted light detector 18. The measurement light source 12 radiates a first measurement light ML1 and a second measurement light ML2 to a plant sample S, the induction light source 14 radiates a first photosynthesis inducing light FR and a second photosynthesis inducing light AL to the plant sample S, and the transmitted light detector 18 detects a first transmitted light TL1 and a second transmitted light TL2. The control unit 20 has an analysis circuit 20a and a control circuit 20b. The analysis circuit 20a calculates a light absorption difference between the first transmitted light TL1 and the second transmitted light TL2, and calculates Y(ND) which is a state in which P700 in photosystem I in photosynthesis has been oxidized as a ROS marker (a reactive oxygen species suppression index) for plants by utilizing the light absorption difference. The analysis circuit 20a diagnoses an environmental stress state of plants by utilizing the ROS marker.

摘要： Sensors having an advantageous design and methods for fabricating such sensors are generally provided. Some sensors described herein comprise pairs of electrodes having radial symmetry, pairs of nested electrodes, and/or nanowires. Some embodiments relate to fabricating electrodes by methods in which nanowires are deposited from a fluid contacted with a substrate in a manner such that it evaporates and is replenished.

摘要： Waterless electrochemical transdermal alcohol sensor. In one embodiment, the sensor includes a proton exchange membrane imbibed with an imbibing liquid that includes at least one cationic substance that is liquid at room temperature. As examples, the cationic substance may be one or more ionic liquids with an imidazolium, phosphonium, ammonium, pyridinium, pyrrolidinium, or sulfonium backbone structure. The imbibing of the proton exchange membrane with the cationic substance obviates the need for the periodic addition of water to the electrochemical cell. The sensor additionally includes a sensing electrode, which is bonded to one side of the proton exchange membrane, and a counter electrode and a reference electrode, both of which are bonded to the opposite side of the proton exchange membrane. The sensor may be incorporated into a wearable transdermal alcohol sensor device, which, in turn, may be incorporated into a system for detecting transdermal alcohol.
