As human body temperature continues to be an early sign of diagnosis, thermometers are found in every clinic and household. Since the inception of medical sciences, thermometers have undergone several developments to bring more accuracy. Triton’s research states that the Global Thermometer Market is estimated to advance at a CAGR of 7.56% during the forecast period 2023-2030.
Due to the environmental toxicity of mercury, the Environment Protection Agency (EPA) recommends phasing out conventional mercury-based thermometers. Thus, infrared radiation (IR) thermometers, known for their speed and accuracy in offering near-instantaneous temperatures, are now widely used. In this regard, Telepower Communication Co Ltd introduced a cost-effective, high-performing infrared thermometer that supports Bluetooth connectivity. Such developments foster the need for more product innovations.
Innovations in Digital Thermometers:
- Smart/Digital Thermometers
The temperature measurement process has been revolutionized with technological innovations. In this regard, traditional mercury thermometers are making a new path for smart and digital thermometers. These contactless, smart heat sensors have the utmost precision in temperature detection.
Smart thermometers are distinguished from the traditional ones with their easy-to-read display and speedy detection of temperature. According to a report by the National Institute of Health (NIH), smart thermometer readings are highly predictive of surveillance data for a respective region and season. The report also found that smart thermometers helped in improving predictions of influenza among the people in California.
- Superconductor Thermometer
Researchers at the National Institute of Standards and Technology (NIST) invented a miniature thermometer in November 2020 with big potential applications. This thermometer is 2.5 by 1.15 millimeters in size and is embedded in another cryogenic microwave device to measure temperature when placed on a chip. Compared to conventional ones, the NIST’s superconducting thermometer is capable of measuring temperatures below 1 Kelvin in about 5 milliseconds.
Thus, being faster, smaller, and more convenient than conventional cryogenic thermometers, the new invention can be mass-produced for chip-scale devices. It can monitor the temperature of processor chips in superconductor-based quantum computers, which must stay cold to function efficiently.
- Ultra-fine thermal sensor
Researchers in Japan have developed a micro-thin thermal sensor. This can be easily attached to the skin to monitor the health of infants. Embedded in a super-fine, thin film, with about ¼ the thickness of human hair, this thermometer measures temperatures between 25-30 degrees Celsius.
Additionally, the materials used to manufacture these thermal sensors are cheap and widely available which ensures a commercialized use of the device.
- FeverPhone App
A team of researchers from Washington University developed an application to measure temperature by placing the smartphone on the forehead. Named FeverPhone, this app allows the touchscreen to gather data and predict temperature within 90 seconds. It analyses interactions between the heat generated by the phone’s battery and the touch of fingers, accurately estimating body temperature without any extra hardware.
Notably, during a test conducted in an emergency department, the application showed impressive results in detecting core body temperatures compared to traditional ones. This eliminates the need to carry separate thermometers and rely on a smartphone for temperature monitoring.
Thermometers Market: Growth Potential Beyond Health Sector
- Increasing Utility in the Manufacturing Sector:
A dominant manufacturing sector and the spillover effects lay the foundation for the growth of the thermometer market. Moreover, as per Triton’s analysis, the Asia-Pacific thermometer market is expected to witness the fastest growth at a CAGR of 8.54% over the forecast period 2023-2030.
Among the ASEAN countries, Singapore, Indonesia, and Thailand are experiencing a robust transformation within the manufacturing sector. Singapore’s industrial manufacturing contributes to around 20% -25% of its annual GDP. Major industry players like HP, Infineon, and Micron look forward to establishing next-generation manufacturing facilities in Singapore to make it among the top five exporters of high-tech goods.
- Rising Importance of Temperature Monitoring in the Food Industry:
According to the World Health Organization (WHO), unsafe food causes 420,000 deaths and 600 million cases of food-borne diseases across the world. Thus, ensuring quality standards throughout the food cycle is important for a seamless process, starting from production to consumption.
Verifying correct temperatures is required during several stages like boiling, thawing, freezing, etc. Consistent temperatures help eliminate harmful bacteria, which minimizes the risk of food poisoning. Probe thermometers are, therefore, critical in food processing facilities, commercial kitchens, or retail settings. It ultimately determines the food safety standards throughout the supply chain.
- Critical use of Thermometers in Research Laboratories:
Temperature records are crucial while conducting deep research, experiments, and scientific investigations. It helps in deriving accurate, data-driven conclusions. Laboratories, research industries, scientists, and environmentalists are completely dependent on thermometers for authentic temperature readings. A slight inaccuracy or a false reading may cause a scientific experiment to fail. Thus, heat-measuring devices help to determine the stability of compounds, the rate of chemical reactions, and the extent of these reactions.
Evidently, the use of thermometers is not restricted to the medical sector. Along with the precision and reliability of products, temperature records play an important role in various other sectors like agriculture, climatology, industrial manufacturing, weather forecasting, and archaeology. This widens the growth potential of temperature-measuring devices, creating opportunities for contenders in the global thermometer market.
