Ingestible Thermo Sensor Performs Core Body-Temperature Monitoring

Feb. 22, 2024
BodyCAP's eCelsius Performance Connect System leverages Insight SiP’s RF modules to perform continuous temperature monitoring.

Leveraging a connected ingestible thermometer for Sports and Occupational Health Research applications, French MedTech BodyCAP has developed the eCelsius Performance Connect System. The solution has connectivity to smartphones and tablets provided by Insight SiP’s ISP1807-LR RF module for continuous core body temperature monitoring.

The thermometer is integrated into an ingestible capsule, which monitors and measures the core body temperature as it passes through the gastrointestinal tract. The innovative connected core body temperature data collection device will transmit data until it's expelled, which usually takes a couple of days but can last up to six days.

The eCelsius Performance research device uses a small 2-cm ingestible electronic capsule, accurate to within ±0.1°C, with a communication protocol for data security. The capsule transmits data via a sub-gigahertz radio to a wearable watch-type device. Called ePerf Connect, the wrist device relays data via Bluetooth, which can be read by any compatible system such as a smartphone or tablet.

Flexible ISP1807-LR Module

Chosen for its high memory capacity and flexible I/O set, the ISP1807-LR module enables the ingested capsule to relay information via Bluetooth in real-time every 15 seconds to 5 minutes. The ePerf Connect then records the data and triggers alerts if the threshold temperature is exceeded.

Insight SiP’s ISP1807-LR RF module's compact size and low power consumption ensures unobtrusive integration with an extended operational life. The module offers a Bluetooth 5 stack along with IPv6 connectivity and Mesh capabilities.

According to Sébastien Moussay, co-founder & Chairman of BodyCAP, “Insight SiP’s RF module is ideal for the connectivity of the eCelsius System, a complex application, requiring fast, reliable processing and best-in-class power consumption. The module’s small size made it ideal for our wearable gateway product, and the sophisticated features allowed it to form the core of this product. Our system is a breakthrough for research and medical applications in which measuring core body temperatures is key to symptom diagnosis and finding the best solutions for patients.”

Dr Nick Wood, director, Sales & Marketing, Insight SiP, added, “We are proud to work with BodyCAP on its highly innovative eCelsius System and contribute our RF expertise and module to enable this connected medical device to provide patients with more effective diagnosis and optimal care.”
