The transient responses of the absolute humidity sensing element and the temperature sensor are specified under the assumption that they correspond to first-order aperiodic factors. Based on the relationships of thermodynamics, Arden Buck equation, and given transient functions, analytical dependencies are...
Since the human body is grounded, the fringing electric field lines stray from the sensor to the hand as the hand approaches the sensor. This technique behaves similarly to the parallel plate equation since the distance between the sensor and GND (hand) electrodes is the only changing parameter...
In the AD fabrication, we can control the density and that leads to excellent humidity sensor and can be used in other application. Aside from low-temperature fabrication and reduced energy costs, previous studies have confirmed other advantages of using the AD method, including efficient film ...
Consequently, the spring-mass deflects linearly according to the Spring Equation. Eq. 5.2.2X=F/kwhereX=deflection of spring−massk=stiffness of spring−mass The resulting deflection of the spring-mass causes the distance between the electrodes and the spring-mass to vary. These var...

However, the parasitic capacitance of the sensor connections can have significant variation due to environmental changes (such as mechanical movement, temperature shifts, humidity changes). These changes are seen as drift in the conversion result and can significantly compromise the system accuracy. To ...
As can be seen from Expressions 1 and 2, the sub position sensor electrodes 800 occupies the same area as the main position sensor electrodes 501, 502, which may be expressed by Equation 3: {x/(m+1)}+{m−(x−1)/(m+1)}=1 That is, it can be seen that any one of the m...
Effect of humidity The relative humidity in the laboratory where the tests were conducted varied between 10 and 20%, as measured by a commercial humidity sensor (#42280, Extech Instruments Corporation, Nashua, NH, USA). To test the system response to moisture, a volume of water was injected...
A sensor element can be any conductive material (for example, a copper PCB plane or a wire). The change can be due to human interaction, such as a finger, ear, or hand. This is often termed capacitive touch, and Figure 2 shows the stackup of a basic capacitive touch design. For ...
