Chemical sensors are a combination of special recognition element and transducers which help in detecting special chemical compounds, also referred to as analyte. Being sensitive to the presence of specific chemical compounds, the recognition element helps in converting the special compound with the help of a transducer, into a generated signal, proportional to the concentration of the analyte.
The chemical sensors can be broadly categorized into electrochemical, gas and other types. Owning to intensive research and advancements in technology, the chemical production and processing is leading to a widespread adoption of chemicals which can be found in biomedical, food, industrial safety, pharmaceuticals, environmental protection and security.
Moreover, manufactures are increasingly using nanotechnology in order to reduce the size of devices. Electrochemical sensors which change when in contact with specific chemical molecules are used widely in the production of nanomaterial-based chemical sensors with respect to their compatibility and wireless communication capabilities.
A growing demand is also observed in the healthcare industry. The industry is continuously undergoing progression in improving the diagnostics of ailments and offers effective treatment development. Ingestible chemical sensors are also used in screening cancer, ulcer and other gastrointestinal problems.
