Carbon particles diused through a silicone
matrix move apart due to thermal expansion
of the matrix, increasing electrical resistance
and reducing power ow.
How it Works
SmartHeat SLT consists of a thin silicone matrix loaded with conductive carbon particles. Electrical current moves
between the carbon particles via quantum tunneling of electrons through the non-conductive silicone material.
The electrical resistance of the material and the current it can carry at any point is determined by the spacing
between the carbon particles, and that the spacing changes with temperature.
As the silicone warms, thermal expansion drives the carbon parti-
cles farther apart and increases resistance point-by-point over the
surface of the heater. At the designed set-point temperature the
heater e󰀨ectively becomes an electrical isolator, drawing negligible
current, and no longer producing heat. Conversely, if the silicone
cools via environmental or load variations, the carbon particles pull
closer together reducing resistance. This allows localized increased
current ow and the heater to produce more heat at that location as
needed to maintain thermal equilibrium.
These e󰀨ects drive the self-limiting nature of this technology
without the need for external instrumentation and control systems.
By controlling the composition of the carbon-silicone matrix in
production, the heater is designed to approach, but not exceed,
a specic temperature set point. When the heater is powered,
it warms to its designed temperature set point and maintains that
temperature within a narrow band.
The SmartHeat Advantage
SmartHeat may be the perfect heater for your application.
Custom designed to maintain a set-point temperature with no programming required
Compact design for simplied manufacturing and use in today’s miniaturized devices
Point-sensitive control for even heating and fast response to environmental change
All-in-one design for reduced purchase and assembly cost
High reliability for reduced maintenance and repair cost
Applications
Many applications can benet from the simplicity and
reliability of SmartHeat. Some examples include:
Keeping batteries warm and condensation-free
for maximum output
Humidifying respiratory equipment for patient
safety and comfort
Safe storage of reagents for accurate analysis
Defrosting of displays for clarity and readability
Defrosting LEDs for safe, clear lighting
Deicing infrared lenses for reliable signaling
Sensor anti-icing for e󰀨ective function
Valve warming to maintain liquid ow
Low-weight deicing of aircraft wings for safe,
reliable operation
Limitations of Traditional Heating Components
Traditional heating components can be very e󰀨ective
at maintaining heat, but they have limitations.
Even if the heaters themselves are compact, they
require external sensors and controllers, which increase
cost, add weight, take up space, and increase system
complexity.
Connections to sensors and controllers complicate
product assembly and become potential points of failure
requiring costly maintenance and repair.
They are either on or o󰀨 and don’t respond to local
changes in temperature unless designed with multiple,
separate zones.
A variety of faults such as delamination or drastic
changes in heat losses can lead to dangerous
overheating.
Simple. Stable. Safe. SmartHeat SLT™
