Current Sensor Market size was valued at USD 3.79 billion in 2024 and is likely to exceed USD 17.31 billion by the end of 2037, expanding at over 12.3% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of current sensor is evaluated at USD 4.17 billion. The growth of the market can be attributed to the growing demand for consumer electronics which includes smartphones, tablets, TVs, and more. In 2022, it was predicted that consumers would spend about USD 500 billion on electronics across the globe. All these electronic products are deployed with sensors. Hence, owing to the growing adoption of these products, the adoption of the current sensor is also estimated to boost.
Moreover, the global market for current sensor is expected to expand significantly as a result of considerable technological developments in the semiconductor and communications industries. Current sensors, which generate a signal that is proportional to the current that is flowing through the wire, are able to detect electric current in a wire. Modern sensor development has led to a decrease in sensor size, which simultaneously increases cost-effectiveness, efficiency, and compatibility. Additionally, their adoption is also growing in industries such as aerospace, agriculture, and medical. Further, sensors are used in automobiles to control the motor drive, the direct current conversion control of the motor's regeneration current, and the detection of the charged and discharged currents of the batteries in electric and hybrid vehicles, all of which are crucial components of control.
Growth Drivers
Rise in Need for Renewable Energy - Global renewable electricity capacity is anticipated to increase by more than 59% from 2020 levels to over 4799 GW by 2026, which is equal to the present total world capacity of nuclear and fossil fuels put together. Through 2026, the expansion in the world's electricity capacity is expected to come from renewable sources virtually exclusively—solar PV would provide more than half. This growing demand for renewable energy can be attributed to rising people awareness regarding growing pollution and rising government initiatives, further also boosting the market growth. Grid-tied systems require current sensors to manage the converters and inverters, optimize the extraction of energy from solar panels, and detect faults for safety. Hence the growing need for renewable energy is estimated to boost the market growth.
Growing Adoption of Electric Vehicles - Despite supply chain snags and the ongoing Covid-19 epidemic, electric car sales hit a new high in 2021. Sales nearly doubled to about 5 million around the world, representing a sales share of approximately 8%, compared to 2020, increasing the total number of electric vehicles on the road to about 15 million.
Surge in Electric Power Station - The quantity of charging stations increased by over a factor of two between 2015 and 2020. More than 55% more charging stations were added in 2021 alone in the United States.
Growth in Telecom Industry - In 2021, in India, there was estimated to be about 659,000 mobile towers, up from approximately 390,000 in 2014. According to this, the number of mobile base transceiver stations has climbed quickly, rising from about 790,000 in 2014 to approximately 3 Million in 2021, an increase of 187%. From about 43% in March 2014 to approximately 57% in October 2022, rural teledensity increases.
Upsurge in Adoption in Laptops - About 276 million laptops are anticipated to be shipped in 2021, together with almost approximately 159 million tablet computers, worldwide.

By End-Use (Automotive, Consumer Electronics, Industrial, Healthcare, Telecom, Renewable Energy)
The global current sensor market is segmented and analyzed for demand and supply by end-use into automotive, consumer electronics, industrial, healthcare, telecom, and renewable energy. Out of which, the automotive segment is anticipated to hold the largest market share over the forecast period. The growth of the segment can be attributed to growing production of electric cars. In the US alone, companies produced 442,000 electric automobiles in 2022. The hybrid electric vehicle (HEV), which is swiftly overtaking all other green vehicles in popularity, uses sophisticated electronic circuitry to regulate the flow of electricity throughout the vehicle. With a single-motor HEV, the motor functions as either a drive motor that runs in parallel with the internal combustion engine or as a generator that powers the regenerative braking system and charges the battery. A typical HEV has a number of electrical systems, such as those for an AC motor and a DC-DC converter, that need electrical current sensors to operate as efficiently as possible.
By Application (Motor Drive, Converter & Inverter, Battery Management, Uninterrupted Power Supply, Grid Infrastructure)
The global current sensor market is also segmented and analyzed for demand and supply by application into motor drive, converter & inverter, battery management, uninterrupted power supply, and grid infrastructure. Amongst these segments, the motor drive segment is anticipated to have a significant growth in the market over the forecast period, backed by its growing use in industries. A motor drive regulates a motor's output horsepower as well as its speed, torque, and direction. A shunt-wound dc motor with distinct armature and field circuits is often controlled by dc drives. Similar to their dc counterparts, ac drives regulate the speed, torque, and horsepower of ac induction motors. However, to insure smooth functioning of these processes the demand for current sensor is growing. The motor's current is precisely detected by the current sensor, enabling flawless synchronization and orientation control. Moreover, there has been growing focus on reducing the usage of energy and reducing the carbon footprint which would also drive the growth of the market.
