Capacitive
sensing is a technology that typically uses human body capacitance as
an input and is based on capacitive coupling. Capacitive sensors
operate by detecting the capacitance of any material to be sensed.
The sensor is automatically switched on when the threshold amount of
capacitance is reached. Capacitive sensors are majorly used for
contactless detection and level monitoring of different objects.
These sensors can be used to detect wide range of materials including
solids, liquids, powders, pellets and others through a non-metallic
container wall as a medium. Unlike inductive sensors, capacitive
sensors are capable of detecting metallic as well as non-metallic
materials. Some of the common applications of capacitive sensors are
detection of surfaces such as paper, glass, wood, plastic, food and
chemical substances. Capacitive sensors are used in packaging systems
to detect and monitor the presence of cardboard boxes and its level.
The capacitive sensors used to detect non-glass materials are usually
referred to as non-glass capacitive sensors. These sensors use
different polymer materials, indium tin oxide (ITO) films and other
non-glass materials for detection.
Non-glass
capacitive sensors market is majorly driven by the rising
electronics industry across the world. Capacitive sensors are widely
used in different touch-screen devices as a replacement to mechanical
keypads. The most popular electronic applications of non-glass
capacitive sensors are smartphone, tablets, mouse touch-pads and
others. With growing demand for touch-screen based electronic
devices, non-glass capacitive sensors are expected to witness high
demand in coming years. Furthermore, non-glass capacitive sensors
offer numerous advantages over the conventional touch detection
techniques such as inductive and resistive detection. Non-glass
capacitive sensors are low cost as compared to the conventional touch
detection techniques and require low power for operation.
In
addition, non-glass capacitive sensors provide high speed, stability
and have longer life cycle. Apart from material detection, non-glass
capacitive sensors are capable of detecting acceleration, motion,
flow and other variable parameters of materials. Thus, these sensors
can be used in large number of applications. However, major factors
affecting the growth of non-glass capacitive sensors market is the
challenges faced in the manufacturing and fabrication process of
these sensors. Additionally, non-glass capacitive sensors are still
in the nascent stage of development, thereby restricting their use in
complex applications.
Non-glass
capacitive sensors market is segmented based on the type of non-glass
materials, applications and geographic regions. The non-glass surface
type segment is further classified into different types of materials
such as polymers, sapphires and other plastic materials. The market
is segmented on the basis of applications into consumer and
commercial applications. Consumer applications of non-glass
capacitive sensors include touch-screen devices such as smartphones,
mouse touch-pads and others. With rising development in touch-screen
devices, non-glass capacitive sensors are expected to witness high
demand in consumer applications. Commercial applications majorly
include ticketing booths, education and training, casino game, point
of interest, automated teller machines (ATM) machines, factory
equipment, medical equipment and other office equipment. Furthermore,
the market for non-glass capacitive sensors is segmented based on
geographic regions into North America, Europe, Asia Pacific and Rest
of the World (RoW).
