초록
현대 헬스케어 기술은 개인의 건강을 실시간으로 모니터링하고 개선하기 위해 발전하고 있으며, 그 중에서압력센서를 활용한 신체 데이터 분석이 주목받고 있다. FSR 기반 압력센서는 낮은 민감도와 정밀도, 내구성부족 등의 한계를 가지며 정밀한 데이터 분석에 제약이 있다. 본 연구에서는 이러한 한계를 극복하기 위해실리콘 유연 소재를 활용한 다채널 압력센서를 설계하였으며, 네오프렌 소재와의 결합을 통해 기계적 강도를높여 내구성을 개선하고자 하였다. 개발된 센서는 실험을 통해 압력 및 저항 변화에 대해 기존 센서보다 더좋은 선형성과 넓은 센싱 범위를 갖는 것을 확인하였으며, 이를 기반으로 한 앉은 자세 분석 시스템을 구현하여 헬스케어 및 웨어러블 디바이스 분야에서의 실용 가능성을 확인하였다.
Abstract
Modern healthcare technology is developing to monitor and improve a personal health in real time and among them, body data analysis using pressure sensors is attracting attention. FSR-based pressure sensors are limited by low sensitivity, poor precision, and insufficient durability, which restricts their use in precise data analysis. In this suudy, to overcome these limitations, we designed a multi-channel pressure sensor using silicone flexible material, and attempted to improve durability by increasing mechanical strength through combination with neoprene material. Experimental results demonstrated the sensor's linearity in pressure and resistance changes, as well as its wide sensing range than existing sensors. Furthermore, a sitting posture analysis system was implemented based on the designed sensor, demonstrating its practical applicability in healthcare and wearable device fields.
