DSruptive concludes world-first clinical study using injectable implants to track body temperature

Study concludes that DSruptives subdermal implants can be used for tracking body temperature – with comparable results to existing clinical methods for temperature measurement.

Between January and March 2021, the company organised a study in cooperation with researchers at Karolinska Institute and Karolinska University Hospital in Stockholm. The study was approved by the Swedish Ethical Review Authority.

The objective of the study was to investigate the feasibility of subcutaneous implants for measuring body temperature in humans. A group of healthy volunteers received one or two temperature sensor-equipped implants which transmitted readings to a smartphone app.
At the end of the study period, the participants were brought into a clinic where their implants were read and in parallel had their body temperature measured with standard clinical thermometers in order to compare the quality of the measurements in a controlled setting.

The study demonstrates that the implants were able to measure temperature with non-inferior accuracy to standard clinical devices. At the same time, the study concluded that implantation of the devices is safe, induces little discomfort and is without adverse effects in the follow up period.

This is the first time a study of this kind has been completed with the results indicating that injectable implants could be a robust, reliable and affordable form of health logging for both personal use and in clinical settings.

Hannes Sjöblad, Managing Director of DSruptive, said,
“It’s tremendously exciting to bring the results of this research to the world – the first time this kind of implants have been properly studied in a clinical environment. The results demonstrate the potential for passive subdermal implants to play an important role in the ongoing paradigm shift towards personalised health and remote monitoring in healthcare.”

Daniel Andersson, head investigator, MD and Associate professor in Physiology at Karolinska University Hospital said:
“The data from this study is really promising and opens up the possibility of deploying temperature monitoring via digital implants in a wide range of physiological and clinical applications. For example, we are currently experiencing the worst medical emergency in a century. With digital implants, we could potentially track outbreaks of COVID-19 or other transmissible infectious diseases more rapidly – with huge benefits for our health, our economies and our societies.”
