Overview



=Project Overview= Electronics and micro-engineering are recent developments in the technological world and are considered as enabling technologies (Baker et al, 1999). Nowadays, micro-technology can be seen in a vast range of industries from engineering, science, manufacturing, telecommunications and even in medicine. Our project will be focusing mostly on the latter, to design and implement a smart sensor system for medical applications.

Through trivial research, it is found that biosignals consists of mostly very low frequencies in a high noise environment. Hence system architectures and technologies require high resolution and high accuracy data processing but may increase power consumption and thus reduce efficiency. Biomedical instruments however require low power consumption and low complexity therefore this project will aim to satisfy these need to reduce the size and cost of the technology.

Instead of clumping all the technology onto one single item, this project aims to separate the intelligence from the sensor and implement a more efficient sensor system where transducers acquire data while a separate device will do the processing, below is a diagram depicting this system. This project however will not focus on the complete fabrication of this device but more on the design, simulation and conceptual theory of the conditioning done by the data acquisition system.
