The system includes a glove attached self-developed ionic liquid-based strain sensors on each finger to detect the movement of them. When the hand move to express a letter lead to the resistance of the strain sensors on each finger change. Therefore, through the information from set of sensors, the system can recognize the letter that user want to convey. A measuring and data acquisition circuit also are developed to receive and analyze data from the sensors. Furthermore, a data digitizing method is proposed as a solution for decoding purpose. The system is tested with 10 distinguished basic letters in American Sign Language table (ASL). The results show the accuracy of system is 98%. The system operates stably with the low power of 0.81W at rest state and 1.71W when working. Besides, applications on smartphone and PC are also built to translate the data into text and speech. These apps make it easier to communicate with deaf people. With achieved results, the system is fully extensible to detect more letters in ALS table in the future date: 2021 date_type: published official_url: http://dx.doi.org/10.1109/ISMEE54273.2021.9774139 id_number: 10.1109/ISMEE54273.2021.9774139 full_text_status: public pres_type: paper pagerange: 263-267 event_title: 2021 3rd International Symposium on Material and Electrical Engineering Conference (ISMEE) event_type: conference refereed: TRUE book_title: 2021 3rd International Symposium on Material and Electrical Engineering Conference (ISMEE) citation: Nhu, Chi Tran and Dang, Phu Nguyen and Thanh, Van Nguyen Thi and Thuy, Ha Tran Thi and Thanh, Van Dau and Thanh, Tung Bui (2021) A Sign Language Recognition System Using Ionic Liquid Strain Sensor.
