For people dealing with spina bifida, paralysis, and various bladder diseases, determining when to take a bathroom break can be an issue. To help ease the frequent stress, researchers at Northwestern University have designed a sensor array that attaches to the bladder’s exterior wall, enabling it to detect its fullness in real time.
In small animal lab tests, the battery-free device could accurately monitor a bladder for 30 days, while the implant lasted in non-human primates as long as 8 weeks. “Depending on the use case, we can design the technology to reside permanently inside the body or to harmlessly dissolve after the patient has made a full recovery,” regenerative engineer and study co-lead Guillermo Ameer said on Monday.
