T his article is a follow-up to the one on SELF capacitance [1], and together, they cover the theories and design guides for the two most popular capacitive sensors, the projected and self capacitive ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Interfacing to MEMS transducers, such as those that sense acceleration, pressure, altitude, humidity, rain, level and gas, e2v's CPIC2.0 ic has been designed to ease the process of sensor data ...

How to build a circuit that converts capacitance into a pulse train. Test results of the circuit design. The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

One of the metrics needed to monitor the success of blood-vessel surgery is blood flow and pressure through the repaired vessel, but measuring that parameter brings many obvious challenges. A team of ...
