Flexible microheaters capable of exerting thermal stimuli in small regions are important for applications in wearable electronics, portable medical instruments, and other space-limited heating devices.
Design Principles of Miniature Flexible Heaters
Heater Geometry and Pattern Design
Coil, spiral, or mesh configurations are what ensure uniform heat distribution. Our ultra-thin silicone construction allows each heater to conform seamlessly to a wide range of shapes and curved surfaces.
Heater Geometry and Pattern Design – ohmvo.comTheir optimal flexibility enables our heating elements to maintain close contact with the surface, even in complex assemblies. In addition, full silicone encapsulation provides superior IP protection, ensuring both electrical safety and long-term environmental durability.
Electrical and Thermal Parameters
Thermal conductivity is further enhanced through our exclusive silicone formulations. Their minimal thickness promotes efficient energy use and enables seamless integration into compact mechanical systems. These characteristics align perfectly with the demanding requirements of thermal management at the microscale.
Substrate Selection and Thermal Coupling
Beyond the exceptional sealing properties of silicone, the various layers of our miniature heaters also incorporate fiberglass for mechanical reinforcement, along with a range of surface coatings that can provide additional features such as anti-adhesive behavior or electrical conductivity for grounding.
Integration of Temperature Sensing Elements
For precise temperature control, we integrate temperature probes (such as thermocouples, PTC sensors, and Pt100 RTDs) directly onto the back of our heating elements. This enables accurate monitoring and real-time temperature regulation.
Materials and Fabrication Techniques
Conductive Elements and Nano-Heater Development
In recent years, our teams have developed nano-heating networks integrated into modified silicone matrices. The incorporation of conductive nanoparticles further enhances the uniformity of heat distribution.
Conductive Elements and Nano-Heater Development – ohmvo.comThe result is exceptionally lightweight miniature heating systems, suitable not only for microfluidic devices but also for applications in aerospace, wind energy, and advanced laboratory equipment.
Integration into Microfluidic and LOC Platforms
Although we have not yet integrated these miniature flexible heating elements into commercial microfluidic or lab-on-chip systems, our technology portfolio already aligns with the key integration principles such systems require. The thinness, flexibility, and high degree of customization of our heating elements ensure theoretical compatibility with common microfluidic substrates such as glass, PDMS, and polymer films.
