A
Newly designed Jell-O-like pill will measure the temperature in
our stomach that, upon reaching the stomach, quickly swells to the size of a
soft, squishy ping-pong ball big enough to remain in the stomach for a long
period of time.
The
inflatable pill is embedding with a sensor that continuously tracks the
stomach's temperature for up to 30 days. If the pill to be removes from the
stomach, a patient can drink a solution of calcium that triggers the pill to
quickly shrinking to its normal size and pass safely from out of the body.
The
pill is made by two kinds of hydrogels and it is the mixtures of polymers
and water that resemble the consistency of Jell-O. The combination enables the
pill to quickly swell in the stomach while remaining it is not allowing the
fluid to the stomach's churning acidic environment.
The
hydrogel-based design is softer, biocompatible and longtime remains more than
current ingestible sensors, which either can remains in the stomach for a few
days, or are made from hard plastics or metals that are orders of magnitude stiffer
than the gastrointestinal tract.
The
Jell-O-like smart pill, that once swallowed stays in the stomach and monitors
the patient's health for a long time such as for 30 days.
It
was designed by inspired of the defense mechanisms of the pufferfish, or
blowfish. Normally a slow-moving species, the pufferfish will quickly inflate
when threatened, like a spiky balloon. It looking ways to design a
hydrogel-based pill to carry sensors into the stomach and stay there to monitor.
If a pill were small enough to be swallowed and passes down the esophagus, it
would also be small enough to pass out of the stomach, through an opening known
as the pylorus. To keep it from exiting the stomach, have to design
the pill to quickly swell to the size of a ping-pong ball.
At
present people are trying to design highly swellable gels, they usually use
diffusion, letting water gradually diffuse into the hydrogel network. But to
swell to the size of ping-pong ball takes hours, or even days.
