Imagine a medical device so tiny it fits through a needle—yet can monitor your brain signals *wirelessly*. A team from China and Singapore just made this sci-fi concept a reality! 🚀
The Future of Brain Monitoring
Researchers at Huazhong University of Science and Technology (HUST) and Nanyang Technological University developed a 2mm hydrogel cube sensor that’s injected into the skull using a simple needle. No invasive surgery required! 💉
How It Works
Once implanted, the hydrogel shifts shape in response to changes in pressure, temperature, pH, or fluid flow. These changes alter ultrasound waves detected by an external probe—like a high-tech game of Marco Polo for your brain. 🎮🧪
Biodegradable & Safe
The sensor dissolves naturally in 18 weeks without triggering immune responses (tested in rats). Pigs trials showed accuracy matching bulkier wired devices—a win for animal *and* human healthcare! 🐷➡️👩⚕️
Beyond the Brain?
Lead researcher Zang Jianfeng says the tech could monitor other organs too. Think of it as a Fitbit® for your insides! Published in Nature, this innovation could redefine neurology and chronic disease care. 📈💡
