Ear-Worn Core-Temp Sensor Global Market Report 2025

The ear-worn core-temp sensor market size has grown rapidly in recent years. It will grow from $0.64 billion in 2024 to $0.75 billion in 2025 at a compound annual growth rate (CAGR) of 16.4%. The growth in the historic period can be attributed to increasing awareness of personal health monitoring, the rising prevalence of chronic diseases, the growing adoption of wearable health technologies, the increasing demand for continuous body temperature tracking, and the expanding health-conscious population.

The ear-worn core-temp sensor market size is expected to see rapid growth in the next few years. It will grow to $1.36 billion in 2029 at a compound annual growth rate (CAGR) of 16%. The growth in the forecast period can be attributed to the rising demand for non-invasive monitoring, greater integration with smartphones and health apps, increasing investments in healthcare technologies, growing emphasis on preventive health, higher adoption among athletes and military personnel, and expanding government support for digital health initiatives. Key trends during the forecast period include advancements in sensor accuracy, innovations in compact wearable devices, development of AI-driven predictive health analytics, improvements in battery life and energy efficiency, and the emergence of multi-parameter monitoring systems.

The rising prevalence of diabetes is expected to drive the growth of the ear-worn core-temperature sensor market. Diabetes, a chronic condition in which the body either produces insufficient insulin or cannot use it effectively, leads to elevated blood sugar levels. The disease is increasing primarily due to unhealthy lifestyles, with high-calorie diets and physical inactivity contributing to obesity, a major risk factor for diabetes. Ear-worn core-temperature sensors support diabetes management by continuously monitoring body temperature, helping detect early signs of infection or metabolic imbalances, common complications among diabetic individuals. For example, in March 2025, the Office for Health Improvement & Disparities reported that the prevalence of type 2 diabetes among adults aged 17 and over in England was 7% in March 2024, up from 6.8% in March 2023. Therefore, the growing incidence of diabetes is driving market demand for ear-worn core-temp sensors.

Key players in the ear-worn core-temp sensor market are advancing technologies with next-generation wearable sensors to improve real-time health monitoring accuracy, user comfort, and continuous, non-invasive temperature tracking. These devices are miniaturized and use innovative materials and wireless technologies to deliver precise, real-time measurements. For instance, in January 2025, CORE, a Swiss developer of thermal monitoring solutions, launched CORE 2, a next-generation wearable body temperature sensor for athletes. CORE 2 is 48% smaller and 30% lighter than its predecessor while offering enhanced features such as LED indicators, modular attachment systems, BLE/ANT+ connectivity, and AI-enhanced thermal energy transfer technology, enabling athletes to optimize performance and heat adaptation during training and competitions.

In June 2025, Corpuls, a German provider of emergency and critical-care medical devices, acquired Cosinuss GmbH to strengthen its mobile and remote patient monitoring capabilities. This acquisition allows Corpuls to integrate Cosinuss’s in-ear vital-sign sensor technology, enhancing continuous mobile patient monitoring and expanding into remote and tactical monitoring applications. Cosinuss GmbH specializes in health platforms for continuous mobile and remote vital-sign monitoring, including ear-worn core-temperature sensors.

Major players in the ear-worn core-temp sensor market are Medtronic plc, 3M Company, Koninklijke Philips N.V., ams OSRAM AG, Masimo Corporation, Melexis, Univera Healthcare, Ticare Health, Oticon Medical LLC, iHealth Labs Inc., VitalConnect Inc., Tempdrop Ltd., Cosinuss GmbH, BodyCap Technologies, Bodytrak, Bios Medical Inc., Custom Technology Inc., Inova Design Solutions Ltd., Equivital Ltd., GreenTEG AG, Eventek, and iThermonitor Inc.

North America was the largest region in the ear-worn core-temp sensor market in 2024. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in ear-worn core-temp sensor report are Asia-Pacific, Western Europe, Eastern Europe, North America, South America, Middle East and Africa.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The fast surge in U.S. tariffs and the trade tensions that followed in spring 2025 are heavily affecting the medical equipment sector, particularly for imported imaging machine components, surgical-grade stainless steel, and plastic disposables. Hospitals and clinics resist price hikes, pressuring manufacturers’ margins. Regulatory hurdles compound the problem, as tariff-related supplier changes often require re-certification of devices, delaying time-to-market. Companies are mitigating risks by dual-sourcing critical parts, expanding domestic production of commoditized items, and accelerating R&D in cost-efficient materials.

An ear-worn core-temperature sensor is a wearable medical device designed to continuously monitor the body’s internal temperature via the ear canal. It utilizes advanced infrared or thermistor-based technology to deliver precise readings that accurately reflect the body’s core temperature. This non-invasive device provides a comfortable and convenient solution for real-time health monitoring, early fever detection, and clinical assessments, eliminating the need for traditional invasive temperature measurement methods.

The product types include disposable and reusable ear-worn core-temperature sensors. Disposable variants are single-use devices designed for hygienic and accurate core temperature monitoring through the ear. These sensors employ technologies such as infrared, thermistor, and other sensing mechanisms, and are available through both online and offline distribution channels. Their applications span healthcare monitoring, sports and fitness, military and defense, and industrial environments, serving diverse end-users including hospitals and clinics, homecare providers, athletes, military personnel, and industrial workers.
