Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...
Figure 7 provides the typical design flow for implementing capacitive sensing. Firmware (F/W) Development, Tuning, and Production Fine Tuning are the critical phases in the life cycle of a ...
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 ...
The quest for energy-efficient designs has made capacitive position encoders a hot topic. • The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize ...
Apple is rumored to replace iPhone's Touch ID home button with alternative bio-recognition hardware when it launches an OLED version of the handset later this year, but the technology enabling that ...
The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a constant current source and a linear monostable formed by two NAND-gate chips (74HC132). The circuit also ...
