Advancement in medical science has now made
it easier for doctor to test human body for signs of diseases. Recently,
wearable sensors has taken place of blood, urine and other type of body test to
examine the human body. Wearable sensors use human sweat. Sweat is chemically
rich source of data to know what is happening inside the human body.
This new technology allows doctors to continuously
monitor the health of human body over a period of time and not just when patients
visits the doctor. With this advancement doctors can provide personalized and
more informed advice to cure patients resulting in better medical solutions and
faster recovery from diseases.
Commercial wearable sensors like gym-watch
fitness tracker or muse headband don’t allow the researchers to examine the
operator’s health on molecular level. Therefore, scientists have introduced
sweat sensitive smart wrist and head bands to sync human health data wirelessly
and in real time to smartphones through Bluetooth.
This invention was tested on 26 people of
all kinds, from athlete to housewife and from infant to aged men or women. Human
sweat comprises of glucose, lactate, sodium, and potassium therefore five
sensory chips are implanted in this device and each one of them keep track of the
following in the human body.
Glucose chip: To keep track of Sugar levels
Lactate chip: Indicates the flow of blood
Sodium and potassium chip: Check for
dehydration and muscle cramps
Skin temperature: To reveal if the body is
over heated
Before this invention none of the previous
wearable sweat readers could monitor all five molecules at one time. One
wearable sensor could judge one molecule and it was generating misleading
information resulting in misguided information and incorrect medications. In
future, researchers aims to add more sensors to the wearable sweat reader and
give clear picture of human body as a whole.
