Apple CEO Tim Cook Spotted Testing Apple Watch-Connected Glucose Monitor

Apple CEO Tim
has allegedly been spotted testing a prototype glucose
monitor that’s connected to his Apple Watch, reports
. Cook, who is said to be aiming to understand how
his blood sugar is affected by food and exercise, has been seen
wearing the device around the Apple Campus.

Cook also mentioned the glucose monitor in a February meeting
with students at the University of Glasgow. It’s not clear if
the device he spoke of in Glasgow is the same one he’s been
wearing around the Apple campus.

“I’ve been wearing a continuous glucose monitor for a few
weeks,” he said. “I just took it off before coming on this

Cook explained that he was able to understand how his blood
sugar responded to foods he was eating. He made modifications
to keep his blood sugar more constant.

Current continuous glucose monitoring systems
require a small sensor that’s worn on the stomach under the skin
to monitor glucose levels. Advanced systems from
include a transmitter, which can display glucose
information directly on an iPhone or Apple Watch.

Rumors have suggested glucose monitoring is the next major health
issue Apple is aiming to tackle. The company is said to have a

team of biomedical engineers
working on developing sensors
for non-invasively monitoring blood sugar levels. Apple is
allegedly working on a continuous monitoring solution that would
not require an under-skin sensor.

Apple’s glucose testing is reportedly far enough along that the
company has started conducting feasibility trials at clinical
sites in the San Francisco Bay Area, and consultants have been
hired to sort out regulatory issues.

According to a
recent rumor
from BGR, Apple could be planning to
add a non-invasive glucose monitoring sensor to a future
version of the Apple Watch, perhaps through the addition of a
smart band that would add functionality to the Apple Watch
without requiring the sensor to be built into the watch.

Cook has said in the past that Apple does not want to put the
Apple Watch
through the FDA approval process
, something that would need
to happen for Apple to introduce a glucose monitor, so a
modular add-on smart band could be an ideal solution for adding
more advanced health tracking features without subjecting the
Apple Watch itself to FDA oversight.
