Spinal injuries can damage the nerve supply to the bladder, meaning that people cannot tell when their bladder is full. This can create excessively high pressure on the bladder, which affects the kidneys and can lead to organ damage.

Researchers at SINTEF, Trondheim, Norway, are developing tiny sensors to measure pressure in the body. The tiny sensor can be inserted under the skin by inserting a thin needle through the skin and into the bladder. The sensor is connected to a thin wire, but the next step would be to make it wireless.

Their long-term goal is to develop sensors that could be implanted for several months or years. Another goal to allow the measurements to be read by a smartphone. That way, any increase in pressure could be detected even when patients are at home, thereby avoiding resource-intensive and uncomfortable examinations in hospital.
