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, able to provide unique functionality, and deliver 3D structures allowing for space and weight savings. 
Sheldahl has 60 years of delivering proven flex circuit content to the automotive vehicle. Sheldahl, from the beginning, delivered the first Flex circuit into the ‘65 Ford Thunderbird; from those early instrument clusters to today’s sensor, heaters, and lighting applications, Sheldahl can demonstrate a history of circuits driven billions of vehicle miles in the harshest of environments.  
Sheldahl is working with automotive industry thought leaders to develop the latest electronic functionality leveraging our vertical integration in material, fabrication, and assembly capabilities. 

Sheldahl's Flexible Circuits & Printed Electronics provide an efficient method of heat displacement.
Creating a safer seat heater is possible through our Flexible Circuits & Printed Electronics.
Heating component

As the automotive industry moves away from traditional combustion engines to electric vehicles, the delivery of comfort to the vehicle's occupants and the battery's temperature control is proving to be a challenge.   
Flexible circuits can provide unique solutions to these problems by delivering heat directly to the battery, seats, floor mats, and steering wheels, improving the MPC (Miles Per Charge). Flexible printed heaters deliver heat more efficiently than traditional air circulation systems. 

Sheldahl Flexible Technologies is currently working with major automotive tier-one suppliers and OEMs to develop new heating and cooling solutions that can adjust to the tight spaces, curved and flat surfaces. Our material and circuit knowledge allow us to design cost-effective solutions that best fit the requirements for various applications.  
Human Machine Interface
Human Machine Interface - Automotive Center Console

Due to the demands of the Automotive vehicle purchaser (you), the interior of an automotive vehicle has transitioned to be a sophisticated computer on wheels. This trend started with the introduction of the first hybrid/electric vehicles and is becoming more evident every day in all new vehicle introductions. The desire to improve the customer experience has led Automotive OEMs (Original Equipment Manufacturers) to replace electromechanical switches with touch sensor technology.   
As OEMs and tier-ones 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 build of material costs.   

Sheldahl Flexible Technologies offer the broadest range (PEDOT, ITO, 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. Partnering with industry experts to develop In-Molded Electronics and smart surfaces. 
In addition, Sheldahl, as a material provider, offers material for use in flat cable tapes for application in FFC jumpers and clock springs.  


LED Interconnect

Interior and exterior lighting is a key differentiator in the OEMs' sale of their models with the development of LEDs, Lasers, and OLED lighting. How many noted the first day run lights developed by Audi or the unique way the Audi signals a change in direction. OEMs and tier-ones balance their desire for differentiation while increasing the aerodynamics to increase MPG (miles per gallon) or MPC (miles per charge), dissipating the vehicles' heat.  
Flex circuits provide a unique trade-off by delivering an interconnect technology that allows for 3-dimensional solutions and thermal performance equivalent to metal core boards. The flexibility of the substrate offers reduced interconnects, lighter and smaller packaging, and system savings.  

Sheldahl was one of the first companies to deliver LED Taillamps, and we had early involvement in the First Day Light Running Lights. This, combined with our thermal and materials expertise, allows us to develop the ideal combination of packaging, thermal performance, and cost. Our material and thermal expertise developed while supplying aerospace applications allow us to select the optimum materials and optimum design to address the CTE mismatch issue inherent when combining Ceramic based LEDs with Metalcore boards.


Battery Management

Electrification in the automobile industry is happening; Monitoring the battery's state and health is a challenge. This requires a flexible and intelligent harness to interconnect to the individual cells, adapting to the expansion and contraction of the battery pack during charge/discharge cycles.  
Flexible Printed Circuits can deliver the cell link 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. Flex Printed Circuits can deliver a smaller and lower weight solution that will enable better MPC (Miles per Charge).  

Sheldahl has decades of experience delivering flexible circuits for the harshest automotive environments. 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, be a partner in developing customized solutions for an evolving, environmentally clean market. 


Seat Sensors

Requires the next generation passive seat sensor to provide proximity, approximated weight, and human presence. In addition, as the Automotive industry shifts to be autonomous, the vehicles evolve from passive to become more active, determining the occupants' health and well-being.   
Flexible circuits as they are in Health Solutions provide the ideal sensor technology for occupancy and biometric sensing. As an industry leader commented, the Vehicle seat is the ideal wearable device, and flex 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. We worked with a key supplier to this industry to develop a technology capable of measuring occupancy and managing the higher-level requirement defined by the OCS.  
Flat Cable Tapes

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 Cable Tapes 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 Flat Cable Tape (FCT) products for clock springs, Wiring for automotive headliners, jumpers/interconnections, and more. If you need a secure and durable connection, we work in prototype development and large-scale production. Sheldahl has the experience, knowledge, and technology to support the most difficult projects customizing our FCTs to your needs.
