IMPLANTS WITH PASSIVE COMPONENTS OFFER 15X LONGER BATTERY LIFE THAN BLUETOOTH
A new implant technology called SWANS utilizes passive components to greatly increase battery life compared to Bluetooth and NFC. With a compact size of 3 x 1.1 x 17 millimeters and the ability to fit a 6 gauge needle, these implants are changing the game in wearable technology.
Testing the system on various surfaces, including chicken breasts, pork belly, and live rats, has shown promising results. Despite the thick texture of pork belly, the signal was able to pass through fat, muscle, bone, and skin, showcasing its exceptional capabilities. The coverage of SWANS implants far surpasses that of Bluetooth or NFC, reaching depths of up to 14 centimeters.
In live rat experiments, signals were successfully transmitted to various implants within the body, demonstrating the versatility of the technology. From subcutaneous to intraperitoneal placements, the SWANS implants proved effective regardless of location.
The most innovative experiments involved strain sensors on rat legs, allowing for limb-specific stimulation based on detected movement. Additionally, an inter-implant relay system was developed to trigger a response only when a specific temperature threshold was reached.
With safety in mind, researchers anticipate minimal risks associated with the technology. In a two-month rat study, scar tissue formation around the implants was manageable, and nerve stimulation remained consistent. The implants’ ability to target specific nerves without impacting surrounding tissues or the heart’s electrical activity bodes well for future applications.
As SWANS technology continues to evolve, its potential for revolutionizing wearable implants is evident. With efficient power consumption, extended battery life, and impressive signal coverage, these implants represent a significant advancement in the field.
