The path towards strengthening smart home gadgets, appliances, and integration lies in the next generation of capacitive technologies.
In this era of smart connectivity, even home appliances are getting in on the action. A broadening portfolio of
electronics solutions and design strategies exist to help
manufacturers innovate sleek and smart appliances. Next-generation capacitive technologies are empowering greater
freedom and economical ways to incorporate enhanced
features to make appliances more functional and fun for
today’s tech-centric consumer homeowners.
Solid-State Capacitive Fluid-Level Sensing
Fluid-level sensing is an essential technology in a range of
modern appliances. Immersed mechanical systems have
traditionally served this role in icemakers, dishwashers,
washing machines, water filtration systems, and beverage
dispensers. The sensors, floats, and switches used in
these systems are immersed in fluid, which can cause
excess wear, corrosion, and even cross-contamination.
Conventional mechanical fluid-sensing systems are limited
to use with standard cylindrical or rectangular tank shapes
in order to yield consistent measurements. The constant
exposure to fluids tends to decrease mechanical accuracy
over time and shorten sensor lifespan.
Appliance manufacturers seeking better design
strategies can now use capacitive fluid-level sensors to
overcome these challenges. Capacitive sensors ensure
precise fluid-level measurements with greater accuracy
and lower set-up costs, utilizing customized end-to-end
solutions and easy-to-install calibration software. The
technology provides greater design flexibility and more
durable, efficient appliance operation than traditional
mechanical systems. The same basic concept used to
make smartphone screens responsive to the touch of a
finger, capacitive fluid-level sensors easily mount to the
outside of a container, and can measure fluid or granular
material through almost any non-metallic material.
