Chemical Sensors Market Size

Chemical Sensors Market size was over USD 22.51 billion in 2024 and is projected to reach USD 69.84 billion by 2037, growing at around 9.1% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of chemical sensors is evaluated at USD 24.15 billion. The growth of the market is primarily attributed to the rapidly increasing use of chemical sensors in healthcare sector to promote the diagnosis application. For instance, chemical sensors for healthcare applications are gaining traction since they are able to provide consistent and real time physiological and chemical information, as well as non - invasive metrics of biochemical markers in human bio fluids such as tears, saliva, sweat, interstitial fluid, and human volatiles.

Chemical sensors are gadgets that convert data about the presence of chemical elements into an analytically useful signal. Chemical sensors are divided into two categories: physicochemical transducers and chemical recognition systems. Chemical sensors that operate mainly in real-time are physically small and are governed by the kinetics and thermodynamics of a chemical reaction. Chemical sensors are widely used in a variety of industries, including the automotive industry, healthcare, aerospace and others. Chemical sensors are also able to monitor increasing pollution level in the environment. Thus, growing adoption of technologically advanced devices in various sectors is fueling up the growth of the chemical sensors market size during the forecast timeframe. For instance, the number of connected IoT devices surpassed 10.5 billion in 2021, and this number is expected to reach 41 billion by 2027.
