Electronic Pill Slowly Delivers Drugs,
The hassle of taking medication every day could someday
be eliminated, thanks to an ingestible electronic pill that lasts
in the stomach for close to a month and releases medication
only when necessary.
A research team from
Institute of Technology
has developed the capsule,
which could be designed to treat
a variety of diseases and disorders
and also enables physicians to monitor
and control dosages using Bluetooth
wireless technology and sensors.
The star-shaped capsule has six
foldable arms that each includes four small compartments
that can be loaded with drugs and sensors. The capsule
is dissolved after the patient swallows it, with the arms
expanding to allow the device to lodge itself in the stomach.
Along with being customized to deliver drugs, the capsule
can include sensors that can alert doctors and patients of
vital conditions and can transmit information and respond to
instructions from a smartphone.
A new technique could reduce the time and discomfort of
adjusting to a new prosthetic knee.
A collaboration between researchers from North Carolina
State University, the University of North Carolina and Arizona
State University has resulted in a new technique that enables
more rapid “tuning” of powered prosthetic knees, allowing
patients to comfortably walk with a new prosthetic device in
After receiving the prosthetic knee, the device is tuned to
Traditionally, a practitioner works directly with the user to
modify a handful of parameters in a process that could take
several hours. However, by using a computer program that
utilizes reinforcement learning—a type of machine learning—
to modify all 12 parameters simultaneously, the new system
allows patients to use their powered prosthetic knee to walk
on a level surface after approximately 10 minutes of use.
