Swallowable Flexible Sensor to Identify Stomach Movements

Scientists at Durch allow us an adaptable sensor that patients can swallow. The sensor stays with the stomach wall and may relay details about stomach peristalsis. This might help doctors to identify disorders that slow lower the movement of food with the gastrointestinal tract, or monitor intake of food in obese patients.

The study team wanted a non-invasive solution for monitoring stomach movements. To do this, they produced an adaptable device for elevated safety. Due to the sensor’s versatility, it may be folded up and squeezed right into a small capsule, which patients can swallow easily. The capsule breaks lower within the stomach and also the sensor adheres towards the stomach wall right after it’s liberated.

“Having versatility can impart considerably improved safety, the way it causes it to be simpler to transit with the GI tract,” states Giovanni Traverso, an investigation affiliate at MIT’s Koch Institute for Integrative Cancer Research.

The sensor includes electrical circuits printed on the flexible polymer. The fabric is piezoelectric, meaning that it may generate an electric current and current when it’s robotically deformed. It’s so sensitive that movements from the stomach wall are sufficient to create electricity within the material, which informs the sensor the stomach is moving.

When testing the machine in pigs, they discovered that the sensor can certainly keep to the stomach wall. Their prototype relayed details about stomach motility, and may tell once the pigs ate food or drank water. The present form of the unit transmits information through wires, however the researchers aspire to design a more elaborate wireless version soon.

The sensor may help doctors to identify digestive complaints that reduce stomach motility. Another application involves monitoring the meals consumption of obese patients. “Having a window into how much of an person is really ingesting in your own home is useful, because sometimes it’s hard for patients to actually benchmark themselves and understand how expensive is being consumed,” states Traverso.
