How can implants communicate with smartphones deep inside the body? The answer lies in a new Bluetooth antenna technology developed by Duisburg-based start-up airCode. This technology makes it possible for implants in the abdomen to establish a wireless connection to smartphones. A clinical study is now to test the system, which involves placing a Bluetooth transmitter in deeper regions of the body.
According to Prof. Dr. Niels Benson, CEO of airCode, this technology was originally developed for a medical technology customer. It enables implants to communicate from a wide variety of body positions. The ability to transmit Bluetooth signals despite the natural signal attenuation in the body is particularly impressive. This was the biggest challenge, as the human body contains water, which strongly absorbs signals in the Bluetooth frequency range – similar to a microwave.
However, thanks to special antenna modules, airCode is able to send signals from the body and receive them on a smartphone regardless of the implant position. This technology has significant advantages as it allows patients to monitor the status of their implant independently. This could reduce unnecessary visits to the doctor and thus contribute to a more efficient healthcare system.
Bluetooth out-of-body communication therefore offers a forward-looking solution that not only strengthens patient autonomy, but also optimizes medical care.
