No economy can achieve success or growth scientifically without research. According to recent studies, the minimally invasive e-Mosquito will automatically draw and test the wearer’s blood throughout the day.

Researchers at the University of Calgary have published after analysing the latest version of their “Wearable Microsystem for Minimally Invasive, Pseudo-Continuous Blood Glucose Monitoring,” a watch-like wearable that “bites” you every few hours to draw blood and test your glucose levels.

According to the research, this novel  system uses a shape memory alloy actuator which contracts when heated and then snaps back into its original form. “When equipped with a small needle, the SMA-based actuators produced much greater penetration force into the skin than the bioelectric actuators and allowed the team to significantly miniaturize the device,” writes IEEE Spectrum. This is obviously not like the recently discovered telescope.

“The  primary concept/idea is to have periodic, spontaneous and autonomous biting resulting in reliable blood testing, said researcher Martin Mintchev. “It’s a very significant step in demonstrating autonomous contact with the capillary.”

The invention can be tailored to asses systems used for diabetes management as well as regular genetic testing or any sort of blood analysis that needs to be done regularly.

 Based on published results:Unlike widespread remedy which tends to calculate and analyse blood sugar  levels from interstitial fluids or tears, our design extracts a whole blood sample from a small lanced skin wound using a novel shape memory alloy (SMA)-based microactuator and directly measures the blood glucose level from the sample.

Furthermore,  In vitro characterization obtained similar result and it shows that the SMA microactuator produced penetration force of 225 gf, penetration depth of 3.55 mm, and consumed approximately 5.56 mW·h for triggering. 
Additionally, the microactuation mechanistic pathways was similarly evaluated by extracting blood samples from the wrist of four human volunteers.  according to the released result, approximately  19 out of 23 actuations efficacously reached capillary vessels below the wrists generating blood droplets on the surface of the skin. 
Furthermore, the integrated potentiostat-based glucose sensing circuit of the e-Mosquito device also showed a  precise and accurate linear correlation (R2 = 0.9733) with measurements using standard blood glucose monitoring technology. Practically, these proof-of-concept studies demonstrate the feasibility of the e-Mosquito microsystem for autonomous intermittent blood glucose monitoring.
In development by the University of Calgary for a decade, the current e-Mosquito prototype is worn on the wrist and made up of two parts. The top part of the device holds the battery, LED display and actuator, while the disposable bottom contains the needle and test strip. With the help of a shape memory alloy, the tiny needle in the device can penetrate a capillary under the skin, painlessly drawing a drop of blood for sampling.

Finally, the  e-Mosquito isn’t somewhat ready for major rock or hit, however, it constitutes a welcoming  move forward for those who have to check their blood sugar regularly.
