Designer's Guide to Rapid Prototyping of Capacitive Sensors on any Surface
This article discusses how to replace the mechanical buttons on a product with a
smooth and sleek touch-sensitive surface. It presents the concept of prototyping
capacitive sensors on any nonconductive surface using silver-ink pens and cop-
per tape. Topics included are capacitive sensor basics, silver-ink and copper tape,
and construction technique. Measured results are presented for sensors applied
to the back side of a simple acrylic sheet. To read more on this topic, click the

Controls & Sensors: Touch Sensors Spread Out
With all the recent excitement about capacitive sensing in portable media players,
laptop PCs and mobile handsets, it is easy to forget that such interface technolo-
gies have been actively designed into major appliances applications for years.
Significant improvements in sensing algorithms and control circuitry have
expanded the suite of applications in which the technology can be implemented.
Designers are seeing the value of capacitive sensing as a replacement for
mechanical buttons and membrane switches, as well as discovering new, exciting
applications such as touchscreens and proximity sensors. To read more on this

White Paper: Cypress’s CapSense Successive Approximation Algorithm
Successive Approximation Algorithm (CSA) is Cypress's new capacitive sensing
algorithm for the CY8C20x34 PSoC device family. CSA enables the implementa-
tion of an array of capacitive sensors through switched capacitor circuitry, an ana-
log multiplexer and digital counting functions. The hardware configuration works in
conjunction with high-level software routines from the CSA User Module found in
PSoC Designer to compensate for environmental and physical sensor variations.
The Art of Capacitive Touch Sensing
Touch sensors have been around for years, but recent advances in mixed signal
programmable devices are making capacitance-based touch sensors a practical
and value-added alternative to mechanical switches in a wide range of consumer
products. This article walks through a design example of a touch-sensitive button
that can be actuated through a thick glass overlay. To read more on this topic,
