The growing use of chemical sensors in the automotive industry is expected to drive the expansion of the chemical sensors market during the forecast period. Automobile traffic is a major source of exhaust gases, and chemical sensors, along with measurement technology, can help enhance engine performance, boost energy efficiency, and reduce pollutant emissions. For example, in January 2023, Bosch, a Germany-based provider of technology and services, introduced new BME690 air quality sensors designed for vehicle integration to monitor pollutants like carbon monoxide and nitrogen dioxide, improving cabin air quality and supplying data to optimize vehicle emissions. The company is also developing a variant of its air quality sensor technology in collaboration with an autonomous vehicle manufacturer, aiming to deliver the first smoke detector capable of detecting smoke and vape within the vehicle. Thus, the increasing use of chemical sensors in the automotive industry is driving the growth of the chemical sensors market.

The increase in various types of cancer is expected to drive the growth of the chemical sensor market in the future. Cancer refers to a group of diseases marked by the uncontrolled division of abnormal cells that can spread to other areas of the body. Chemical sensors are specifically designed to detect certain biomarkers associated with different cancer types, allowing for accurate and non-invasive screening and monitoring of cancer-related molecules. For example, a report published by the American Cancer Society, a US-based health organization, in January 2022 projected that there would be 609,360 cancer deaths and 1.9 million new cancer cases in the US in 2022. Additionally, around 10,470 pediatric cancer cases and 5,480 cancer diagnoses among teenagers are anticipated in the same year. Thus, the rise in various types of cancer is propelling the growth of the chemical sensor market.

An emerging trend in the chemical sensors market is the integration of Artificial Intelligence (AI). AI is being increasingly employed in chemical sensors to identify and quantify the complex mix of chemicals in the environment. The collaboration between chemical sensors and AI allows for precise identification and categorization of target gases, demonstrating high selectivity and sensitivity. In November 2022, King Abdullah University of Science and Technology (KAUST) developed an AI-based chemical sensor capable of identifying specific gases in the air with impressive precision. This technology has applications in medical diagnostics and the detection of hazardous industrial gas leakages. The incorporation of AI algorithms enhances the capabilities of chemical sensors, providing specialized and accurate gas categorization models for a wide range of applications. This trend showcases the ongoing innovation and potential growth in the chemical sensors market.

Major players in the chemical distribution market are actively introducing new products, with a focus on innovative solutions such as hydrogen pressure sensors. These sensors are designed to measure the pressure of hydrogen gas, catering to various applications. In September 2023, Baker Hughes, a prominent US-based energy technology company, launched Druck hydrogen-rated pressure sensors. Engineered for prolonged stability and resilience in challenging conditions, these sensors find utility in diverse applications such as gas turbines, hydrogen production through electrolysis, and hydrogen filling stations. The incorporation of advanced barrier coating technology ensures the durability of these hydrogen pressure sensors in demanding environments over extended periods. The technology safeguards the sensor element from the adverse impacts of hydrogen, guaranteeing customers an exceptional minimum operational life of five years across a broad pressure spectrum. This innovative product not only endures challenging hydrogen conditions but also offers heightened precision and reliability, providing customers with a valuable tool in their operations.

In January 2024, ABB, a Switzerland-based engineering firm, acquired Real Tech Inc. for an undisclosed sum.
