Electrification, sensors, infotainment, interior, and exterior lighting, and the potential for autonomous functionality are transforming the automotive vehicle into a sophisticated electronic device on wheels. This increased electronic content demands a circuit technology that can be folded, fit into small spaces, provide unique functionality, and 3D structures allowing for space and weight savings. 
Sheldahl has been providing Flexible Circuits to the automotive industry for almost 60 years. Sheldahl provided the first Flexible Circuit into the ‘65 Ford Thunderbird and from those early instrument clusters to today’s sensor, heaters, and lighting applications, demonstrating a history of circuits that have been driven billions of vehicle miles in the harshest of environments.

Sheldahl's Flexible Circuits & Printed Electronics provide an efficient method of heat displacement.

Heating component

As the automotive industry moves away from traditional combustion engines to electric vehicles, the delivery of comfort to the occupants and controlling battery temperature is proving to be a challenge.
Flexible Circuits can provide localized heating to the battery, seats, floor mats, and steering wheels, improving the MPC (Miles Per Charge). Flexible printed heaters deliver directed heat more efficiently than traditional air circulation systems.

We are currently working with major automotive Tier 1 suppliers and OEMs (Original Equipment Manufacturers​​​​​​) to develop new heating and cooling solutions that adjust to tight spaces, curved or flat surfaces, providing lower weight options. Our material and circuit knowledge allow us to aid in the design of cost-effective solutions that best fit the requirements for various applications.

The Automotive interior has transitioned to essentially become a sophisticated computer on wheels. The desire to improve the customer experience has led Automotive OEMs to replace electromechanical switches with touch sensor technology.

As OEMs and Tier 1 suppliers work to transition mechanical buttons and switches to touch sensors, flex circuits can play a key role. They can be integrated into tight, curved, or flat surfaces, converting plastic surfaces into smart surfaces. Flex circuits can meet these challenges while reducing assembly and bill of material costs.

Sheldahl Flexible Technologies offer the broadest range (PEDOT, ITO (Indium Tin Oxide), Nano Silvers, Silver, Carbon, Etched Copper) of flexible and dependable touch sensor solutions to address multiple applications within the automotive vehicle. We are an innovator in transparent capacitive touch, including haptic feedback. As a part of our continuous improvement effort to meet market demands, we are always developing new technological capabilities.

Automotive Interior LED Lighting

Interior and exterior lighting is a key differentiator in automotive design. Flexible Printed Circuits provide unique solutions by delivering 3-D interconnect technology with enhanced thermal performance. The flexibility of the substrate offers fewer interconnects, lighter and smaller packaging, and system savings.

Sheldahl was one of the original providers of LED (Light-Emitting Diode) tail lamps, and then daytime running lights. Our thermal and materials expertise enables us to co-develop the ideal combination of packaging and thermal performance, addressing CTE (Coefficient of Thermal Expansion) mismatch in high-power LED applications.


Battery Management

With the electrification of the automobile industry, the monitoring of the battery's state and health is critical. This requires a flexible and intelligent harness to interconnect to the individual cells, capable of adapting to the expansion and contraction of the battery pack during charge/discharge cycles.
Flexible Printed Circuits can effectively link the cells to the vehicle's electronics. The necessary electronic components can be surface mounted to the FPC, while the inherent flexibility allows for the battery pack's expansion/contraction. These flexible technologies can deliver a smaller and lower-weight solution that will enable better MPC (Miles per Charge).

In addition to the monitoring of battery cells, we have been developing and designing heaters for batteries. These thin-film applications can be sandwiched between the individual cells to significantly reduce charging time and extend the overall lifetime of the battery in cold climate conditions.  

Our vertical integration provides the broadest range of material, fabrication, and assembly capabilities in the industry. We excel in the collaborative development of new technologies. Our technically experienced staff can help you optimize battery management interconnect and be a partner in developing customized solutions for an evolving, environmentally clean market.


Seat Sensors

The next generation of automotive developers are creating active autonomous devices on wheels, enabling vehicles to measure the health and well-being of the occupants through seat sensors.
Flexible Printed Circuits provide the ideal sensor technology for occupancy and biometric sensing. Our biometric sensing experience in the Health industry is an enabler for future requirements in Automotive seating. As an industry leader commented, the vehicle seat is the ideal wearable device, and flexible circuit technology is the ideal solution for curved, tight spaces and flat surfaces.

Sheldahl is a leader in passive seat sensor technology for the Automotive market, working with key suppliers to develop technologies capable of measuring occupancy and manage the higher-level requirements defined by the OCS (Occupant Classification System).
Flat Flex Cable (FFC) Insulation Material
Flat cabel

As the automotive industry moves toward creating safer vehicles developing a better connection between the driver and the vehicle is paramount. The steering wheel becomes the key connection point for interfacing effectively, integrating humans and computers, working together for a safer and more comfortable driving experience.

  Flat Flex Cable (FFC) Insulation Materials provide the ideal connection technology for curved, tight spaces and flat surfaces, capable of repeatedly turning back on itself for years of use.

Sheldahl produces various insulation materials in the development of FFCs used for Clock Springs, wiring for automotive headliners, jumpers/interconnections, innovative solutions, and more. Sheldahl has the experience, knowledge, and technology to support the most difficult projects customizing our materials to meet your needs.
