Researchers have developed a new soft, flexible, battery-free implant that sticks to the bladder wall to detect fullness.

Do you need to go to the bathroom immediately, or can you wait until you are home? Someday, there might be a special device in your body and a phone app that can tell you exactly when you need to go, so you won’t have to guess anymore.Subsequently, it wirelessly sends concurrent data to a smartphone app, enabling users to track their bladder fullness in real-time.

Similarly, the bladder contracts to release pressure as it empties. Strain-level data is picked up by sensors which is then transferred to a smartphone or tablet using embedded Bluetooth technology. The system provided continuous bladder measurement in small animals for 30 days and in non-human primates for eight weeks. It accurately detected even low urine volumes.

According to researchers, this allows surgeons to rebuild or reconstruct the bladder without removing intestinal tissue, which is the current clinical standard for this procedure.

Improving Comfort and Battery Life with VR Headstrap Battery StrapEvery hardcore VR user knows there are two important things when it comes to daily VR gaming: comfort, and battery. One accessory that can improve both of those things is a headstrap that houses a built-in mobile battery, or a “battery strap”. Let’s face it, the stock strap that comes with the Quest 3 is a complete joke. It almost offends me that Meta raises their prices every year and continues to find materials from the dollar store to make their stock strap. Thus, users have no option but to buy a new one, and Meta bets on that. That’s why they keep doing it and they make it simple to plug and play new straps into the headset; .
