Chemiresistors are a type of chemical sensor that depends on the chemical reaction between the analyte and the detecting material. Covalent, hydrogen, or molecular recognition bonds can be formed between the detecting substance and the analyte to cause interaction.
According to the chemical reaction between the analyte and the sensing material, chemiresistors function as resistive chemical sensors. Covalent bonds, hydrogen bonds, or even molecular recognition can be the basis for this interaction between the sensing material and the analyte.
A chemical sensor is an apparatus that transforms a physical or chemical characteristic of a specific analyte into a quantifiable signal proportional to the analyte concentration.
The Global Chemiresistive Sensor Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Chemical sensors are becoming more widely used to examine the chemical makeup of various samples, which is why they are being adopted.
Higher-order orthogonal sensors, for example, are inexpensive and portable, which are important trends in the worldwide market and are anticipated to support the market under analysis expansion.
The main advantages of chemical sensors are their capacity to function without an electrical connection to the sample and their tolerance to harsh environmental conditions (such electromagnetic interference, high temperatures, and high pH levels).
Due to these properties, numerous fiber-optic chemical sensors have been developed for analytical uses in the medical, environmental, and industrial fields.
The market includes the usage of chemical sensors for analytes in the chemical industrial process in addition to environmental concerns. The market is being driven by sensors, which are being used as cutting-edge machinery in the healthcare, research, and defence sectors.
Because of the interaction between analyte and transducer, optical sensors depend on fluctuations in optical analysis (light intensity or wavelength). The interaction alters the levels of ambiance lighting. The physical quantity of light was measured and converted into electrical signals to assess whether an analyte was present.
In the oil and gas industries, traditional sensors are also less precise in measuring low-concentration chemicals because they are difficult to maintain, require air-conditioned shelter rooms, require frequent calibrations, and can be influenced by other chemicals.
