The performance of high-temperature, polymer-based RH sensors was investigated in order to evaluate their long-term stability. The work is aimed at understanding how severe temperature cycles may alter the characteristics of relative humidity (RH) sensors, how they impact the measurements, and how ...
Conductivity exaggerates the amount of capacitance that is front of the sensor by bridging the effect of the sensors field to a larger volume. This will cause capacitive sensors to become stuck in an ON state when only a tiny amount of material in front of the sensor is connected to a lar...
I've been trying to get these moisture sensors to work for 4 hours but i just cant seem to! I've tried everything i can think of 3.3v, 5v, different sensors(but the same) differnet cables, different pins, pull up, pull down etc etc, ive tried attenuation but not much. it either...

Another common fingerprint scanner type used today is the capacitive scanner. While these types of sensors were once common on the back of smartphones, they’re now commonly embbedded within side-mounted power buttons instead. Foldable smartphones like theGoogle Pixel 9 Pro FoldandGalaxy Z Flip ...
The characterization and tracking of biological cells using biosensors are necessary for many scientific fields, specifically cell culture monitoring. Capacitive sensors offer a great solution due to their ability to extract many features such as the bio
These sensors are cheap, however, the circuitry required to interface them to other devices is not. [Petteri Hyvärinen] is successfully investigating the use of capacitive touchscreens for heart rate sensing among other applications. The capacitive sensor layer on modern-day devices has a grid ...
