A Wearable Face Shield: Pioneering engineering invention

The Department of Electronics and Communication Engineering is proud to announce the remarkable achievement of the students Chebrolu Taraka Sai Tanishq and Vellampalli Medha V Subrahmanya Aditya. They have designed a wearable face shield and secured the second position in IEEE Covigilance, 2021 – A pan India student contest based on Covid-19 relief do it yourself equipment design and development, under the guidance of Dr Anirban Ghosh, and got a patent published for their prototype developed as part of the competition. The team also participated in the 4th Research Day organized by SRM University-AP and received a gold medal.

The prototype was submitted in the design competition on July 30, 2021, and after 40 days of rigorous brainstorming, component procurement and prototype development, the final model was submitted for evaluation. Based on prototype execution, feasibility of manufacturing and suitability of the model to contain the spread of the pandemic, the team secured second place in the Pan India contest, and it was deemed fit to address the two criteria; innovation challenges like Innovation of homemade masks/shields/PPEs and innovation of a feasible solution to control covid-19 spread while the schools and colleges are reopening. Further, this prototype was submitted to the patent office under the name “A Wearable Face Shield” (Application no:202241000990) and the patent was published on January 21, 2022.

Their accomplishment bears testimony to the fact that unflinching determination towards your goals and consistent efforts to make them come true will always pay off. Designing a wearable face shield is a well-timed innovation as the pandemic shows no sign of retreat and face shield has become one of the daily necessities of all mankind.

About the Prototype

The wearable face shield is a medical protective device, and it comprises a frame for securing the shield to the head of a wearer, a transparent sheet extending from the frame, a detection circuit that is mounted on the frame, a switch, and a battery module. The detection circuit comprises of a control unit that processes the sensed data received from proximity and temperature sensors to generate output signals and an alerting unit that comprises LEDs, buzzer and it provides an indication of– (i) the presence of a detected external object within a pre-determined distance of the wearer (ii) the sensed body temperature of the wearer. The alerting unit is placed strategically to alert people via visual and audio signals respectively.

Such precautionary detection and proximity alert prototype can prove instrumental in early diagnosis and isolation aiding in crowd management and free movement in places of social gathering. Hence, a wearable face shield ensures adequate separation between persons and facilitates temperature monitoring and early detection of disease.

They are currently working on a project called “Human Monitoring System” (HUM). It is an all-pervasive system designed to measure and keep track of the heartbeat, blood pleasure, temperature, location, Spo2 level etc of the user. In the event of an emergency or critical drop in any of the vitals, the system can automatically alert the local hospital, ambulance service and relatives.
