The text discusses a breakthrough in implant technology using SWANS (Smart Wireless Autonomous Neuro-implants). Here are the key points:
-
Power Efficiency: SWANS implants use passive components, allowing them to draw minimal power while in listening mode, significantly extending battery life compared to Bluetooth and NFC technology.
-
Implant Size: The complete implant with a battery is compact, measuring 3 mm x 1.1 mm x 17 mm, and can be inserted through a 6-gauge needle.
-
Experimental Testing: The system was tested in various contexts including chicken breasts, pork bellies, and living rats, illustrating its capability to transmit signals through complex tissues.
-
Signal Penetration: A single 10-volt pulse can create detectable voltage gradients over 30 cm across different tissues and reach depths of up to 14 cm, surpassing Bluetooth or NFC range.
-
Advanced Applications: In experiments with rats, the team demonstrated remote stimulation where movement sensors in the front legs transmitted signals to the hind legs, causing them to twitch. They also created a relay system that triggered signals based on temperature readings.
-
Safety: The technology operates within safe voltage ranges similar to those used in existing medical devices like pacemakers. In a two-month study, while scar tissue formed around the implants, communication remained effective, and safety measures were in place to prevent unwanted nerve stimulation or adverse effects on heart activity.
This innovative technology has significant potential for medical applications, offering improved communication and stimulation capabilities in implants.
