COVID-19 IMPACT

Disruption in Supply Chain Hindered Short-term Growth During COVID-19 Pandemic

• The COVID-19 pandemic and related restrictions created new opportunities for using the device in different applications, such as in Robotics and UAVs, considering social distancing norms.


• Companies have felt the impacts of the COVID-19 pandemic in the resulting political and economic uncertainty in global conditions. The stability of credit and financial markets, decrease in consumer confidence, and decline in customer spending also negatively affected the market.


• Due to supply chain disruptions at different locations, major corporations relating to space programs, satellite manufacturers, automotive industries, and agencies cancelled or remodified their programs due to the COVID-19 pandemic. This factor has impeded the MEMS ecosystem and has impacted the navigation sensors sector. The cancellation of orders has impacted supply chains across regions.


• To reduce the spread of the coronavirus, governments in several nations limited the number of personnel in manufacturing enterprises. As the pandemic restrictions increased, several businesses have suffered financial losses.


• Many companies, including Analog Devices Inc., focus on strategic partnerships, mergers, and acquisitions to retain and increase their customer base.


• New York-based firm Eaglehawk developed a way to sanitize large areas against COVID-19 via disinfectant drones.


• Telepresence robots, originally designed for offices, became an invaluable tool for medical workers treating highly infectious diseases such as COVID-19, reducing the risk of contracting the pathogen.


• In the U.S., startup Zipline deployed its fixed-wing autonomous aircraft to connect two medical facilities 17 kilometres apart. 


• Since all these applications require an IMU, the COVID-19 outbreak provided new growth opportunities.

DRIVING FACTORS

MEMS is one of the most promising technologies of the 21st century, with the potential to revolutionize industrial and consumer products. It combines silicon-based microelectronics with micromachining technology. The increasing use of MEMS devices in advanced navigation, advanced automotive applications, electronics, communication, defense, and medical sectors is expected to increase the use of the IMU sensor in MEMS devices.

• During the pandemic, the world witnessed severe chip shortages in the MEMS and IC industries. This factor will drive investment and growth in the industry.


• Increasing applications of wearable devices, such as smart watches monitoring body temperature, breath, and heart rate, are causing the MEMS market to grow.


• The pandemic has boosted the interest in flexible printed sensors due to the increased demand for medical devices to monitor vital functions. The growing relevance of printed sensors and devices in the medical and pharma industry is a major driver for the industry.


• The growth of autonomous vehicles and electric vehicles, the beginning of the adoption of hydrogen power plants, and increased environmental monitoring will facilitate the growth of the MEMS market.


• According to Qeexo, developer of the Qeexo AutoML, and Bosch Sensortec GmbH, ML algorithms created using Qeexo’s AutoML can be deployed on Arduino Nicla Sense ME with Bosch BHI260AP and BME688 sensors. With this, they can be used for monitoring environmental parameters and capturing information embedded in motion such as person-down systems to fitness apps that check posture.

Increasing Demand for Robotic Systems to Boost Inertial Measurement Sensors Adoption

Position and movement information for a robot can be checked with such a device. Inertial measurement unit is also used to control and operate the robot wirelessly. An increase in demand for wireless robot control is a major driver of this market. They can be programmed to perform dangerous or repetitive tasks with consistent precision and accuracy. Thus, industrial robots are increasingly used in a variety of industries and applications. These robots make use of inertial sensors.

Inertial measurement devices with inertial sensors are mainly used in robot applications such as dynamic motion and terrain compensation, payload platform stabilization, and antenna and camera pointing applications.

RESTRAINING FACTORS

As IMUs are Prone to Errors, there is an increase in Navigation Errors and Heat Dissipation over a Period of Time

The information on the motion of the IMUs is transmitted to the Inertial Navigation System (INS). These measurements are used as input in the INS filter. The result of combining this information with GNSS information gives position, velocity, and attitude. Such measurements can be integrated concerning time. Hence, any errors in the measurements grow over time.

The bias errors, if not removed from the measurement, get integrated twice as part of the mechanization process. Due to this, a constant bias in acceleration becomes a linear error in velocity and a quadratic error in position.

Gyroscopes and accelerometers may be subjected to a change in the bias based on how the sensor experiences acceleration. It is very common in Micro Electro Mechanical Systems (MEMS) gyroscopes when the mass undergoes acceleration along the sensing axis. These errors can significantly affect navigation.
