Development of a Wearable Biosensor System for Ubiquitous Healthcare Applications

Abstract:

With the development of wearable computing, wireless communication and artificial intelligence technology, the physiological monitoring systems for homecare applications achieved more and more attention. It is a challenge to design a fully integrated circuit satisfying the requirements of wearable biosensor system, such as small size, low power consumption, wireless transmission, and high signal noise rate (SNR). Based on these considerations, we recently developed a fully-integrated circuit for a wearable biosensor system to measure multiple vital signs in real time, meanwhile, we adopted FIR notch filter to remove the 50Hz power line interference and used cubic spline interpolation to reduce baseline drift noise. The experimental results showed that this wearable system ran well, which could be applied for real-time and ubiquitous healthcare in daily life.
