Many people like to talk about how advanced technology is
damaging our way of life by eliminating more and more jobs. Although that is true for a lot of
professions, technological advances are also improving our way of life by
making us healthier and safer. A common
trend today is the wearing of different fitness trackers such as Jawbone Ups,
Fitbits, and FuelBands that use internal sensors to monitor calories burned,
heart rates, severity of sleep apnea, and even slouching (Jones). This type of sensor technology is a wonderful
way of encouraging people to be more aware of their health. Although these wearable sensors are being
sold to the masses for increasingly lower costs, the future capabilities of fitness
and medical sensors will be able to monitor and track areas of health that is
harder to control and measure.
The National Institute of Biomedical Imaging and
Bioengineering (NIBIB) already have the ability to connect a brain to a
computer using wired connections, but want to use that technology to create a
sensor that could “lead
to unobtrusive, thought-controlled prosthetics and other assistive devices for
people with amputated limbs, paralysis, or other movement impairments.” (Sensors) Although this is a large hurdle for researchers
to overcome, it’s only a matter of time before it becomes a reality. It is likely that implanted sensors in the
brain could then be connected to other sensors in the body to manipulate and improve
other deficiencies such as blindness by connecting the brain sensors with
others that may be implanted in an eye.
Another area of ongoing research is using biological sensors
for medical improvement. One example of this
is by using “engineered cells that can be ‘programmed’ with
receptors that latch onto specific
brain chemicals. The resulting chain of activity causes a protein within the
cell to change color that researchers can detect” (Sensors).
Allowing scientists to monitor brain activity in this way can give
insight to possible mental disorders. It can also be used to fight diseases such as
HIV that are often hidden in cells and have
processes that can be hard to monitor.
One problem with biological sensors is that our bodies tend to want to
fix anything that doesn’t belong, including sensors. Research at the NIBIB is trying to improve
sensor abilities against our bodies’ natural defenses by “creating novel types of
coatings that improve sensor sensitivity, selectivity, and
stability” (Sensors).
As mentioned in Tyler’s post, future sensors will need to be
able to adapt to their environment to be more effective. Additionally, Audrey’s post mentioned that
future sensors need to be able to consume energy from surroundings to remain
cost-effective. While one would like the
health of a person to remain steady and in good standing, vital signs and other
chemical processes are constantly changing and affecting the health of a
person. Sensors located throughout the
brain and elsewhere in the body will need to employ adaptive measures and
utilize energy produced by the body to remain both cost-effective and fully
functional.

You brought up an interesting point about our bodies wanting to get rid of foreign objects. In this scenario, it wouldn't be that the sensor works or can collect/relay the information, but can it survive in a harsh environment. Then the designers have to think about how the coating they apply to protect the sensor effects the sensors ability to collect/relay information.
ReplyDeleteI liked how you brought the point of how biological sensors can also be used to combat diseases. I wish there was a deeper discussion on exactly how this can be done, but the idea of an "internal vaccine" that also provides other benefits is something I'm looking forward to in the future.
