Building Toward the Integration of PSoC and Bio-medical Instrumentation Abstract
As part of its quality instruction enhancement plan, the University of Houston is transforming undergraduate learning experience through research. This transformation aims to improve student learning by providing and expanding research experience and its importance to society. This paper discusses some representative undergraduate research experiences that integrate emergent technologies with existing biomedical devices. It describes both the current implementation and future plans for signal conditioning system design in order to accommodate multiple services and interface types. It will also discuss the benefits, cost and space savings through this integration and implementation of PSoC-based interface to bio-medical instruments.
Introduction
Today various bio-medical instruments are being integrated with wireless sensor networks in order to monitor patients and send critical patients’ information from remote site. The feature will allow for the portability of hospital monitoring systems to become integrated with the available wireless communication systems. Due to their low signal power and relatively higher noise to signal ratio, however, wireless signal transmissions require a carefully designed signal conditioning system. There has been an increased amount of research on wireless medical sensor networks in order to improve and/or change the traditional service provided by medical professionals to their patients including manual data collection, paper registration as well as using hand held radios for communication. In1, the authors present the challenges medical service providers face due to unreliable data communication infrastructure, limited resources and less information when a disaster occurs. Today most of the studies introduce the automation of patient care paradigm besides the feasibility of scalable wire sensor networks, its effectiveness, flexibility and better performance for monitoring and tracking patients. The concept of using body area network of sensors for data detection and transmission through PDAs were presented in2, 3. There have been further studies in terms of using highly extensible and modular wireless sensor platforms such as the miTag4 which is used to gather and transmit patient critical data for both short range and long range network of sensors. The miTag has been integrated with various types of sensors including temperature sensor 5, GPS6, blood pressure7 and ECG8.
Part of the solution to low signal transmission level is using new and emergent technologies such as the Programmable System on Chip (PSoC) in the design of system interface for signal conditioning as well as data acquisition systems. Microprocessors/microcontrollers have been available for several years and today designers can take advantage of increasingly sophisticated programmable components and software configuration tools. A PSoC is a powerful and highly configurable system on chip architecture for embedded control design. It includes both code-free and high level language programming modes in one package. The innovative and unique qualities of the Cypress’ PSoC based design allow designers to dynamically reconfigure their products by utilizing fewer components to perform a given task. In the next section the details of PSoC from both the hardware and software perspectives will be presented. This paper based on
