National University of Singapore completed Research Trial on continuous, non-invasive Core Body Temperature using multiple-sensor technology with improved accuracy from Well Being Digital (WBD101)

(Hong Kong, China) - The Department of Physiology, Yong Loo Lin School of Medicine, National University of Singapore (NUS), conducted a study led by Dr. Ivan Cherh Chiet Low on improving the accuracy of body core temperature monitoring, which is crucial for minimizing heat injury risk, using multi-sensor ear-based wearable. They found that when they incorporated the external auricle temperature into the earbuds, the predictive accuracy improved, suggesting that it can account for environmental influences on the aural canal. This research lays the groundwork for the future development of a continuous ear-based physiological monitoring system that could offer protection in heat-exposed activities and vulnerable populations.

The Paper on "External auricle temperature enhances ear-based wearable accuracy during physiological strain monitoring in the heat" can be found published here https://www.nature.com/articles/s41598-024-63241-2

Recognizing the critical need for accurate and continuous core body temperature monitoring, Well Being Digital Limited (WBD101) embarked in this collaboration to support the modifications of the earbuds with additional sensors. This joint endeavor aims to develop cutting-edge technology capable of continuously detecting tympanic temperature, which is located in the ear canal adjacent to the eardrum. Tympanic temperature measurement has been widely recognized as a practical, non-invasive and probably the best method for monitoring core body temperature, particularly in emergency settings. This is primarily due to the tympanic membrane's shared blood supply with the hypothalamus, the brain's temperature regulation center. This anatomical and physiological connection allows the tympanic temperature to closely mirror the body's internal, or core, body temperature.

When monitoring body temperature, it's crucial to understand that not all body sites provide the same level of accuracy. Measurements taken from the chest, finger, wrist, and forehead, for instance, represent skin temperature. Skin temperature is influenced by both the body's core temperature and the surrounding environment. As such, it is typically lower than the body's internal or core temperature. Skin temperature can fluctuate significantly due to various factors. Moreover, physical activity can also affect skin temperature as increased blood flow to the skin is a key mechanism for heat dissipation during exercise. In contrast, core body temperature remains relatively stable, as it is regulated by the hypothalamus, the body's thermostat. Therefore, while skin temperature measurements can provide useful information about the body's surface heat exchange with the environment, they are not representative of core body temperature, and therefore not a medically accepted indication of the body physiological condition.

"We continue to enhance our core body temperature sensing technology and A.I. algorithm" says Mr. Wallace Wong, Co-Founder of WBD101 and Chief Technology Officer https://www.linkedin.com/in/wallace-wong-4157531/, "we are grateful that NUS has validated the accuracy in this research trial to be within 0.28℃. We are also grateful to Texas Instruments for their TMP117 support, iTemos Inc for the deployment and Grandsun Electronic for their 233621 Sense earbuds".

"Core Body Temperature is one of the key vital signs monitored in-hospital, for out-of-hospital applications the importance of continuously monitoring is increasing important especially due to extreme weather and climate change." says Mr. Kow Ping, Co-Founder of WBD101 https://www.linkedin.com/in/kowping/, "The publication of this paper is a huge milestone for the collaboration with NUS on Core Body Temperature that started since 2018. The progress of the research trial has not been easy considering the onset of Covid-19, non-critical work had to be halted during this period especially since we needed subjects to get their body temperature up to 39.5℃, we thank the NUS team for their professionalism and commitment".

WBD101 collaboration with NUS leverages their extensive research capabilities and WBD101 technological expertise to refine and enhance this method of continuous, core body temperature measurement. The goal is to create a device that not only improves patient care outcomes but also advances the understanding of human thermoregulation. This technology has the potential to revolutionize temperature monitoring in various fields, from healthcare to sports science, by providing accurate, continuous and non-invasive core body temperature readings implemented on common devices that can also function as an earbuds.
