Heavy duty industries are adopting smart, networked technologies, including the Internet of Things (IoT) and Artificial Intelligence (AI), which has led to the increased use of human machine interfaces (HMIs) in various products and applications. HMIs are essential components that offer control and merge physical and digital data in a user-friendly display. However, engineers face material challenges in designing and manufacturing HMIs for harsh environments, such as extreme temperatures, vibration, and contamination. To address these challenges, companies like Boyd are developing solutions that utilize resilient materials and expertise in converting these materials into various shapes and sizes. Key considerations for HMIs in harsh environments include high brightness and contrast, glare control, and weatherability, as well as the ability to withstand road conditions, vibration, and heat. Materials such as foams, tapes, and adhesives play a crucial role in ensuring thermal and electrical contacts, preventing damage, and protecting HMIs from short circuiting and mechanical failure. Additionally, thermal management is critical to improve HMI durability, and deploying special heat spreaders and thermal interface materials can help transfer heat away from critical components. Electromagnetic interference (EMI) is also a concern, and addressing it requires the use of materials and technologies that can manage electrical and signal noise.
