Abstract:
Leveraging the air-trapping features of the lotus leaf, recent advancements in pressure sensors have introduced a unique aero-elastic capacitive pressure sensor using a gas-liquid-liquid-solid multiphasic interface. This innovation significantly enhances pressure sensitivity and reliability in challenging liquid environments due to its minimal hysteresis, excellent linearity, and negligible threshold effects. It promises to enable sensitive and reliable intra-body monitoring and improve surgical precision where biomechanical pressure sensing is necessary.

Capacitance: Single-Phase And Three-Phase Line
Single-Phase Lines
Consider a single-phase, two-wire transmission line with equal phase spacing energized by a voltage source. One conductor carries a uniform positive charge, while the other carries an equal negative charge. The capacitance C of the line can be derived from the voltage V between the conductors. For a one-meter section of the line, the capacitance is given...
