Bowel sensor could help tackle incontinence

Leader of the project team, Herriot-Watt’s Dr Michael Crichton, explained that the flexible sensor could be mounted on the large intestine in order to measure how the tissue moves and strains during bowel movements. 

“The sensor will track the stool as it moves through the body, and turn the data into an early warning system for the user,” said Crichton. “People’s lives are badly affected by faecal incontinence, and it’s compounded by the fact that few people feel comfortable or confident to talk about the issue.

“Discreet digital technologies could help people monitor and manage their bowel condition and have more active, confident lives.”

Crichton said that the sensor's design makes use of flexible electronics and flexible strain measurements in addition to audio measurements, allowing for identification of motion. The behaviour is then transmitted to an app for interpretation.

"Developing a technology that can be delivered in minimally invasive way and not interfere with the normal function of the organs is a big challenge," he commented. "By understanding the attachment surfaces and its movement, we can tailor the technology to minimise any risk of failure or adverse patient impact."
