capacitive sensing are touch detection with gloves, higher RF immunity, elimination of false detections, Braille-friendly touch sensing and water immunity.
Electrical reactance, the opposition to a change in voltage due to capacitance (capacitive reactance) or in current due to inductance (inductive reactance)
Electrically short antennas have considerable capacitive reactance, so to make them resonant at the operating frequency an inductor (loading coil) is added in series with the antenna.
Individual, tile-like modules—each containing LED (Light-emitting diode) lighting and capacitive sensors—are connected in an open-ended array.
His research interests involve biological applications of Microelectromechanical Systems (MEMS) and acoustics, especially: microfluidics for low cost CD4 counts for HIV in resource-limited-settings for global health problems; acoustic picoliter droplets for cell-by-cell 3D tissue generation, and semiconductor applications; capacitive micromachined ultrasonic arrays (CMUTS) for medical imaging applications.
Bill Mensch pointed out that Fmax depends on off-chip factors such as the capacitive load on the pins.
Zytronic designs composite component touch technologies that optimise the performance of electronic display applications and manufacture projected capacitive technology based touch sensors and their associated controllers which are used in public access and industrial applications.

As a result the touch display can be completely protected from external factors and has a far greater resistance to rough treatment of all forms – abrasion, shock, vibration, extreme heat levels, adverse weather conditions and exposure to harmful chemicals in contrast with other traditional touch sensing techniques, such as optical, acoustic, capacitive, infra-red or resistive screens.
