The phrase "a perspiration sensor" is correct and usable in written English.
It can be used when referring to a device or technology that detects or measures perspiration, often in contexts related to health, fitness, or wearable technology.
Example: "The new smartwatch features a perspiration sensor that helps track hydration levels during workouts."
Alternatives: "sweat detector" or "sweat sensor".
A perspiration measurement system composed of several sensors was developed.
And then a nice smiley man with a perspiration issue comes and sings a song.
The device is loaded with sensors, which beyond using the accelerometer to measure sleep patterns, include an optical scanner to track blood flow (i.e. heart rate), a perspiration monitor, as well as skin and ambient temperature monitors to measure workout intensity, heat dissipation and so on.
Ali Javey, a materials scientist and professor of electrical engineering and computer sciences, has combined innovative materials, sensor technology and integrated circuits to develop a wearable sweat sensor network that can measure rapid fluctuations in electrolytes and metabolites, and even the buildup of heavy metal concentrations in perspiration.
The application describes technology that could be fitted to headphones or earbuds and that uses a skin sensor to measure biometric data including temperature, perspiration and heart rate.
Checks include: A moisture sensor in the transmission knob tests your perspiration for the presence of alcohol; A Face-monitoring camera in the dash determines if you appear to be cognizant of your surrounds, i.e., about to propel several tons of metal down a highway; an air sensor detects alcohol.
Perspiration on the skin surface was estimated by using a capacitance sensor to measure the amount of moisture on the palm, forehead, and philtrum before and after a heating stimulus.
Your personal habits are stored, along with your dietary intake and vital signs, thanks to improvements in perspiration-reading sensors, wireless communications with menus, and heart-monitoring wristwatches.
A chemical sensor in the wristwatch detects surges in chloride ions in the wearer's perspiration.
