Wireless Sensor Networks for Home Health Care
TL;DR: The goal of the work is to focus on health-related applications of wireless sensor networks and how current (and future) technologies will enable automated home health monitoring.
Abstract: Sophisticated electronics are within reach of average users. Cooperation between wireless sensor networks and existing consumer electronic infrastructures can assist in the areas of health care and patient monitoring. This will improve the quality of life of patients, provide early detection for certain ailments, and improve doctor-patient efficiency. The goal of our work is to focus on health-related applications of wireless sensor networks. In this paper we detail our experiences building several prototypes and discuss the driving force behind home health monitoring and how current (and future) technologies will enable automated home health monitoring.
Summary (1 min read)
- Various economic and technological factors (e.g. Moore’s Law) have brought sophisticated electronics within the reach of average users.
- One important benefit is to help stem rising health care costs by increasing health observability and doctor-topatient efficiency.
- More specifically, this paper will discuss several of these projects, highlighting their need, design, implementation, and results.
- Demonstrate working prototypes with relatively simple technology which make incremental, but important, steps to toward ubiquitous deployment of health monitoring devices, as well as how they may be integrated into existing infrastructures.
- The authors prototypes use two similar sensor network mote technologies: Tmote Sky and SHIMMER.
- The Tmote Sky is the latest derivative of the Berkeley Telos motes from Moteiv Corp. .
- The other mote is Intel’s Digital Health Group’s platform for Sensing Health with Intelligence, Modularity, Mobility, and Experimental Re-usability, or SHIMMER.
- Both are nearly identical with respect to processing and communication; each have the Chipcon CC2420 802.15.4 radio and TI MSP430 (with 10k RAM).
- The authors have developed several prototypes which demonstrate wireless sensor network technologies for heath care at home.
- Each of these prototypes will be discussed in the following sections.
- If people with a severe hearing impairment are included with those who are deaf, then the number is 4 to 10 times higher.
- At least half of these people reported their hearing loss after 64 years of age .
- The deployment of mote technology further reduces the cost of their prototype.
- Once the measured signal surpasses the reference value, an encrypted activation message is sent to the Base Station that incorporates the Transmitter address.
- Figures 5(b) and 5(c) shows the manufactured Base Station and Transmitter prototype that were successfully tested and evaluated.
- Sophisticated, low-power, cheap, small, and mobile electronics will continue to permeate the home environment for a variety of applications, ranging from multi-media entertainment to home automation.
- Therefore, this figure shows that hospital costs will rise sharply and health-care at home is one way of alleviating this problem.
- Several technologies will be important to this evolution: sensor networks, RFID, and mobile consumer electronics.
- Software may be deployed on these devices to remind patients of their responsibilities (e.g. taking their pills and how much to take) and performing real-time analysis of patient data, given parameters set by their physician.
- Falling electronics prices and their increasing power, coupled with sensing technologies, promise to make health monitoring in one’s home, rather than frequent trips to the hospital, a reality.
- These prototypes represent incremental, but important steps towards ubiquitous deployment of health monitoring devices for the betterment of human lives.
