Printed Flexible Heaters and Warming Elements

Printed Heating & Warming Elements

GSI printed heating element PTC automotiveGSI creates fully printed resistive heating elements with conductive low resistance traces and unique high resistance arrays for heating surface applications, can create self temperature controlling heaters utilizing positive temperature coefficient (PTC) technology, or print thermocouples to measure temperature. By control of dimensions and ink compositions these products offer precise resistance specifications without the need for resistor trimming. Printed PTC heaters have found wide acceptance in markets such as Automotive, Healthcare, Food Services, and Consumer Goods. GSI has served many customer designs, some of which include:

  • Automotive seat heating
  • Heaters to aid in surgical healing and recovery
  • Patient therapeutic comfort heaters
  • Food temperature control containers
  • Battery testers
  • Deicing systems
  • Apparel

Static Resistive Heating Technology

GSI will produce custom designed flexible heating elements with highly conductive electric bus delivering uniform power to individualized point resistive heaters or to a uniform resistive heating layer. Resistive materials are stable across temperature regions and fully printed without laser trimming.

Positive-Temperature-Coefficient (PTC) Technology

Printed flexible heaters are produced at GSI in high volume using positive-temperature-coefficient (PTC) resistors. These constructions may be designed to operate in a steady state or self-limiting modes to achieve desired temperatures. PTC technology can self-regulate operational temperature due to resistance change with temperature. The current draw of the heater decreases as the heater warms and will eventually reduce such that the heater will no longer maintain temperature. As the system cools, the current will rise again causing the heater to maintain an operational temperature. Some of the capabilities GSI has to offer:

  • Positive Temperature Coefficient Technology (PTC) useful in producing self-regulating heaters
  • Unique item level identification with 100% electrical testing
  • High quality uniform heaters due to real time online statistical process control
  • Integration of thermochromic layers to identify temperature change
  • Roll or sheet manufacturing
