Over the past decade, smartwatches have evolved from simple activity trackers into
advanced health monitoring platforms. Features such as heart rate monitoring, blood oxygen
measurement, sleep tracking and ECG have become standard in premium devices.
Multiple global trends point to the fact that the next major step for smartwatches will be
continuous and reliable Core Body Temperature (CBT) monitoring, the measurement of the
body’s true internal temperature.
Unlike many traditional wearable metrics, CBT provides direct insight into the body’s
physiological state and can indicate changes related to recovery, stress, illness, hormonal
fluctuations and physical performance. This is why CBT is increasingly being viewed as one
of the next key parameters within digital health and next-generation smartwatches.
Historically, however, the technology required to estimate CBT has been too clumsy, too
expensive or too complex for integration into mass-produced consumer devices. Most
smartwatches today still rely on skin temperature measurements, which are heavily
influenced by environmental conditions and provide limited real time insights into the body’s
actual condition.
At the same time, the smartwatch market continues to grow rapidly. According to Fortune
Business Insights 1 , the global smartwatch market was valued at approximately USD 38.5
billion in 2025 and is projected to exceed USD 105 billion by 2032, representing a compound
annual growth rate (CAGR) of approximately 15.4%.
JonDeTech has developed a patented digital sensor technology designed to enable
continuous CBT measurement in compact smartwatch and other mass market wearable
applications for consumers. The company’s sensors combine ultra-thin form factors, low
power consumption and cost-efficient high-volume manufacturing capabilities, characteristics
that are increasingly important as smartwatch manufacturers compete to deliver more
advanced health monitoring features in smaller and more energy-efficient devices.
The strength of JonDeTech’s technology lies not only in the sensor itself, but also in the
combination of hardware, software and algorithms designed to enable accurate and
continuous temperature monitoring in small, non-invasive consumer products.
Market interest in CBT-enabled wearable applications continues to increase. We are
engaged in 20+ customer projects within wearables and digital health, where companies are
evaluating how CBT can create new user value and differentiate future smartwatch and
health-focused consumer products.
The broader wearable technology market is growing even faster. According to
MarketsandMarkets 2 , the global wearable technology market is expected to expand from
approximately USD 84.5 billion in 2025 to around USD 176.8 billion by 2030, corresponding
to a CAGR of approximately 15.9%.
Leading technology companies are investing heavily in digital health, while consumers
increasingly demand more relevant and personalized health insights. As smartwatches
evolve from fitness accessories into proactive health tools, the demand for more reliable
physiological data is expected to increase rapidly.
The ability to continuously estimate core body temperature in real time may therefore
become one of the most important enabling technologies in the next generation of
smartwatches.
For JonDeTech, this represents a highly attractive opportunity. With a scalable sensor
platform, a growing number of customer projects and several commercial discussions
underway, the company is positioning itself for the next phase of growth within smartwatch
and wearable health technology.
Cut in short, the smartwatch market is entering a new phase and we have high hopes that
our technology will play a key part. Core body temperature is likely to become as important
as heart rate in the next generation of connected health devices.
