This enables to make actual changes in business. This shift from mere sensing to sense making is expected to lead to complete sensor digitalization thereby open large opportunities for sensor manufacturers.
7. Innovation Driven R&D Investment
With large investments flowing into R&D, innovation is an integral part of sensors with over 56 emerging sensors/gauges/meters developed in the past few years. These emerging sensors are expected to grow strongly at 18.4% CAGR till 2023. Samsung Electronics announced in late 2019 a plan to invest $100 billion for sensor development to tap the lucrative global sensor market. Samsung in early 2020 developed first 108MP sensor in the market for smartphone applications.
Similarly, recently Sony invested to develop a new 64MP 0.8um sensor. Companies like Honeywell, Emerson, Yokogawa, TE, First Sensor (TE) GE, Baker Hughes GE, Endress+Hauser, iEE, Omron, ST Microelectronics make large investments from 3-10% of their annual revenue to develop game-changing sensors and technologies. Many sensor manufacturers partner with R&D companies like Fraunhofer to develop innovative sensors. The quantum leap in investments in sensor upgradation and development is likely to cause an explosive growth in this decade.
8. Acoustics, A Single Technology Platform Addresses Multiple Unmet Needs
Acoustics, an inexpensive technology is at the forefront to address unmet needs. In September 2020 rapid Ebola detection biosensor was developed by Sensor Kinesis that eliminates enriching sample thereby reducing test time drastically to just under an hour. R& D efforts recently were successful to address number of sub-sea and oceanographic applications using acoustic technology platform. Underwater acoustic sensor systems and sensor networks was designed to enable applications for oceanographic statistics collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance applications.
9. Exponential Demand for Infrared Temperature Sensors
Temperature check at the point of entry to any establishment became the hallmark of COVID-19 detection for both symptomatic and asymptomatic humans. Temperature check using non-contact temperature meter, like infrared temperature gun, became most important part of CDC and public health authorities’ guidelines. Hand-held non-contact infrared (IR) forehead thermometers have experienced sudden exponential demand as tools for measuring body temperature as part of COVID-19 related mitigation measures, due to their rapid, non-invasive, and hygienic approach to preventive health monitoring. Estimates indicate at least 300% increase sales of IR thermometers in 2020 alone.
