Regular assessment of core temperature plays a critical role in the early detection of infection and clinical deterioration. For at-risk populations— including post-operative patients, individuals at risk for sepsis, immunocompromised patients, and those with complex medical conditions—continuous temperature surveillance can provide valuable clinical insight. As higher-acuity care expands across the hospital and into transitional and home settings, healthcare providers need reliable temperature monitoring solutions that reduce clinical burden while helping to facilitate timely intervention. The collaboration between Philips and Blue Spark Technologies helps address this need by extending continuous temperature monitoring across the care continuum.
At-a-glance:
- Philips’ partnership with Blue Spark combines its wearable disposable TempTraq® device with Philips monitoring ecosystem infrastructure.
- TempTraq® provides high frequency body temperature monitoring for up to 72 hours.
- The integrated solution supports continuous temperature monitoring across the care continuum—from acute care hospitals and oncology units to step-down settings and home-based care programs—supporting early fever detection for high-risk patient populations.
- Temperature data can integrate into Philips patient information center (PIC iX).
- This partnership reinforces Philips’ commitment to integrated vital sign monitoring solutions across care environments.
Advancing Continuous Temperature Monitoring Through Collaboration
Philips has partnered with Blue Spark Technologies to integrate the TempTraq® continuous temperature monitoring patch into the Philips patient monitoring ecosystem. TempTraq® is a single-use, wearable adhesive patch that continuously measures body temperature for up to 72 hours, providing clinicians with high-frequency data without adding to their workflow.
Unlike periodic spot checks, continuous temperature monitoring offers ongoing visibility into a patient's temperature trends over time.
Unlike periodic spot checks, continuous temperature monitoring offers ongoing visibility into a patient's temperature trends over time. When combined with other vital sign measurements, this data contributes to a more comprehensive view of patient status and can help clinicians identify changes that may warrant further assessment.
The solution also extends monitoring beyond the hospital. Patients can continue to wear TempTraq® at home, helping them remain connected to their care team during recovery. Temperature data can be transmitted to Philips PIC iX, where it can be viewed, trended, and monitored through centralized dashboards and mobile devices. By supporting continuity of monitoring across acute care, lower-acuity settings, and the home, the integrated solution helps clinicians maintain visibility into patient health trends throughout the care journey. This connected approach may support earlier discharge for appropriate patients while helping to identify potential complications before they lead to readmission.
Extending clinicians’ line of sight by integrating temperature trends into existing workflows supports Philips’ strategy of advancing patient monitoring capabilities through collaborative innovation.

Key reasons why Philips joined forces with TempTraq®:
- Shown to detect fevers up to 28.2 hours earlier than standard of care in a prospective clinical trial (Lin et al., 2025)
- Trusted by hospitals and pharmaceutical customers worldwide
- Soft, comfortable patch
- CE and FDA-cleared class II medical device
- Operating life of 72 hours
- Disposable/single use
- Wireless Bluetooth (low energy)
- Appropriate for all ages and all skin types
- Temperature display in Fahrenheit or Celsius
- Audio and/or visual notifications of rising temperature
- Connectivity to Philips ecosystem
Clinical integration
In the hospital, the TempTraq® wireless wearable continuously transmits patient temperature data, helping to reduce the need for additional manual temperature assessments. The data can be then integrated into Philips PIC iX, where it can be viewed alongside other physiologic measurements at the central monitoring station, helping clinicians maintain a more complete picture of patient status.
Beyond the hospital, TempTraq® supports continuity of monitoring during recovery at home. Temperature data can be integrated into Philips PIC iX, where it can be trended alongside other available patient information to provide ongoing visibility into changes over time.
A unified view of patient information can also support coordinated workflows, communication across care teams and more informed clinical decision-making
By combining continuous temperature monitoring with other physiologic data within a connected monitoring ecosystem, clinicians gain a more comprehensive view of the patient across the continuum of care. Bringing together information from multiple care settings helps maintain visibility into patient status as individuals transition from hospitalization to recovery at home.
A unified view of patient information can also support coordinated workflows, communication across care teams and more informed clinical decision-making. This connected approach helps bridge the transition between acute and post-acute care, supporting a more continuous and personalized care experience.
