Current Sensor Market Trends and Dymanics:

Driver: High adoption of Hall-effect current sensors

Hall-effect current sensors are mainly used for current monitoring, overcurrent fault detection, and power measurement in the industrial automation, telecommunication, and utility sectors, as well as medical, aerospace & defense, consumer electronics, automotive, and railways industries. Currently, industry players are manufacturing completely integrated and programmable current sensors based on bipolar complementary metal-oxide semiconductor (BiCMOS) or complementary metal-oxide semiconductor (CMOS) technologies. These current sensors exhibit features such as no insertion loss, low power consumption, compact package size, single or dual power supply, high accuracy and sensitivity, galvanic isolation, and fast response time.

The surging adoption of Hall-effect sensors in advanced applications, such as autonomous cars and robots, is expected to spur the current sensor market growth. For instance, the ACS714 30 Amp Hall-effect current sensor module provides economical and precise solutions for AC or DC current sensing in robotics and automotive applications for autonomous devices. Magnetic sensors used in these applications are highly efficient, accurate, reliable, robust, and have a simple design. The manufacturers of magnetic current sensors are highly investing in different magnetic sensing technologies, such as tunnel magnetoresistance (TMR) and giant magnetoresistance (GMR), to enhance their domain expertise and strengthen their market position. Moreover, the players are also expanding their current sensor product portfolios by introducing new products to cater to the needs of various end users. For instance, in August 2023, Texas Instruments Incorporated (US) launched TMCS1123, a lowest-drift isolated Hall-effect current sensor for high-voltage systems and a portfolio of current shunt monitors that eliminate the need for an external shunt resistor for non-isolated voltage rails.

Restraint: Intense pricing pressure resulting in decline in average selling prices (ASPs)

Increasing applications of current sensors in EVs, HEVs, consumer electronics, telecommunication equipment, and healthcare devices have increased its overall shipment, but sales growth has been hampered due to the continued fall in the price of a product over time, due to pressure from customers and competitors. Several companies are channeling their research and development activities toward providing cost-effective current sensor solutions that use MEMS technology and developing IoT-compatible sensors. This has resulted in pricing pressure, especially for applications where current sensors are used in a high volume. Consequently, manufacturers have been compelled to decrease the potential price of current sensors. Reducing the average selling price benefits the customers but shrinks the profit margin of suppliers. The main challenge for the companies is to offer improved quality products and reduce the overall cost of production. Thus, intense pricing pressure has resulted in a decline in average selling price (ASP), which is expected to hamper the growth of the highly competitive current sensor market.

Opportunity: Miniaturization of current sensors

The miniaturization of current sensors is a key trend in the current sensor market. This is driven by the increasing demand for current sensors in a variety of applications, such as wearable devices, medical implants, power grids, electric vehicles, and control systems. Certain benefits associated with miniaturization of current sensors are reduced size and weight based on application, improved performance, lower cost compared to larger sensors, and enhanced integration with other electronic components.
There are certain challenges associated with miniaturizing current sensors, but to overcome these challenges, several techniques are available. For instance, one of the key challenges is the need to maintain accuracy and sensitivity as the sensor is miniaturized. This can be achieved by using new materials and fabrication techniques.

Another challenge is the need to reduce the power consumption of miniaturized current sensors. This can be achieved by using low-power electronics and optimizing the sensor design.

Some techniques that can be used to miniaturize current sensors are the use of new materials , such as graphene and carbon nanotubes, to make current sensors smaller and more sensitive; the use of new fabrication techniques, such as 3D printing and micromachining, to create miniaturized current sensors with complex geometries; the use of integrated circuits to reduce the size and power consumption of current sensors; and the use of wireless communication to transmit the output of current sensors to a remote location, which can reduce the size and complexity of the sensor.

The miniaturization of current sensors is a rapidly developing field, and new techniques are constantly being developed. This is a promising trend that is expected to continue in the coming years, as it will enable the development of new and innovative applications for current sensors.

Challenges: Need for product differentiation and development of innovative solutions

Current sensors require proper and timely maintenance and replacement to avoid problems related to accuracy, drift, and sensitivity. Currently, in the current sensor market, Hall-effect and magnetoresistive (AMR, TMR, and GMR) are among the most widely used sensor technologies. Hall-effect and AMR sensors have been in the market for a long time. Hence, players need to differentiate their products from competitors by innovating products and providing customized magnetic sensor solutions. Companies are trying to innovate their products according to the changing requirements to capture the maximum share of the sensor market. Magnetoinductive and magneto-optical sensors are being used for customized sensor applications.

Magnetic current sensors offer high accuracy, dynamic range, and faster response for power conversion applications such as power supplies for datacenter, servers, and telecom; motor drives and inverters; and uninterruptible power supplies (UPSs). Also, conversion and power management applications in next-generation electronic devices are increasing, which require magnetic current sensors that deliver reliability, durability, and accuracy.

Automotive segment account for the largest market share of the current sensor market, by end user, during the forecast period.

The automotive industry holds the largest current sensor market share and is projected to retain its position during the forecast period from 2023 to 2028. With the growing adoption of electric vehicles, there would be significant advancements and growth in the use of current sensors. Since battery is the main source of energy for systems in hybrid electric vehicles (HEVs)/ electric vehicles (EVs), it is important to know about its charging-discharging cycles. Current sensors are the main source of information for this charging-discharging cycle, and it also reports the status of the battery’s state of health (SOH) to the battery management system. They may be located onboard or externally. With the increase in battery capacities of HEVs/EVs, the requirements for higher current ranges are increasing, thereby accelerating more demand for current sensors.
