Recent decades have seen a revolution in automotive safety, helping preserve the lives of countless drivers and passengers worldwide. OEMs are now turning to advanced electronics and artificial intelligence (AI) to continue to improve modern vehicle safety. Features that help mitigate the effect of driver inattentiveness, inexperience and error that were once just luxury vehicle options are now standard options on most new models on the progressive journey to full level 5 autonomy. These features are known today as advanced driver assistance systems (ADAS).

ADAS market trends and predictions

ADAS currently incorporates technologies such as video transmitter (VTX) sensors, ultrasound, cameras, radar and lidar. These technologies are at the core of many safety and convenience features that have become common in modern vehicles, such as blind-spot detection, emergency braking, adaptive cruise control, lane departure warning and parking assist.

According to a report by Fortune Business Insights, the ADAS market is forecast to grow from $27.52 billion in 2021 to $58.59 billion in 2028. This represents a CAGR of 11.4%. Multiple factors are driving this growth.

Consumer demand

According to a 2022 survey by AutoPacific, 75% of consumers want features such as automatic emergency braking, with 40% of respondents over age 60 wanting it regardless of price. Meanwhile, 80% of respondents want rear cross-traffic alert with rearward emergency braking.

Technological innovation

AI and improved automation promise to take ADAS features to even greater levels in the future. Next-generation ADAS will enable the driver to further disengage from the act of driving in certain situations. The end game is the Level 5 fully autonomous vehicle, in which the passengers cede complete control to the vehicle’s AI.


To date, ADAS has not been addressed by regulation in the U.S. However, a law in the EU, which took effect in 2022, mandates electronic safety features in new motor vehicles. These features include lane-keeping assistance, advanced emergency braking, speed assistance, parking cameras and data recorders.

The continued adoption of ADAS technology requires components to be easy to assemble, lightweight, durable and cost-effective. ADAS and supporting components must perform flawlessly across a wide range of environmental conditions, including exposure to fuels and chemicals, temperature extremes, road salt and UV light. They must also be durable to last the length of a vehicle’s life. According to the U.S. Department of Transportation, the average age of vehicles on U.S. roadways is now 12.1 years.

Key engineering challenges for ADAS

Many OEMs and tier suppliers specify the use of functional materials featuring pressure-sensitive adhesives to address various engineering challenges related to ADAS design. These functional materials include gaskets, thermal interface materials (TIM), electrical and thermally insulative materials, films for light management and lens protection, and die-cut tapes for general bonding.

Challenge: EMI shielding and RFI protection

Electromagnetic interference (EMI) and radio frequency interference (RFI) reduce electronic signal integrity and strength, which can cause disturbances and poor performance in sensitive communication systems andFigure 3: Generally, shielding first deflects  electromagnetic waves with reflective surfaces. Source: BoydFigure 3: Generally, shielding first deflects electromagnetic waves with reflective surfaces. Source: Boyd devices. EMI can be a severe safety concern in ADAS applications. Robust engineering design is needed to prevent and protect against it.

EMI/RFI shielding solutions from Boyd reduce electronic malfunction susceptibility by blocking unwanted external electromagnetic waves or by preventing internal electromagnetic waves from emitting and interfering with other circuits or devices in and around ADAS components.

These solutions balance electrical conductivity, dielectric permittivity, magnetic permittivity and physical geometry to inhibit the transmission of EMI/RFI. Generally, shielding first deflects electromagnetic waves with reflective surfaces. This process heats the shield, making moderate electrical and thermal conductivity important characteristics of EMI/RFI shielding.
