Personal Area Network

摘要

As electronic devices become smaller, lower in power requirements, and less expensive, we have begun to adorn our bodies with personal information and communication appliances. Such devices include cellular phones, personal digital assistants (PDAs), pocket video games, and pagers. Currently there is no method for these devices to share data. Networking these devices can reduce functional I/O redundancies and allow new conveniences and services. The concept of Personal Area Networks (PANs) is presented to demonstrate how electronic devices on and near the human body can exchange digital information by capacitively coupling Pico amp currents through the body.rnFor example wearing a PDA that puts out an on-body signal that contains your professional contact information-a business card. The PDA also monitors body signals from similar devices that are sending business card data from other people. When you shake hands with a similarly equipped person, your PDAs automatically exchange business cards. Of course if your PDA can " recognize" a person that you met before, it can provide you with data you have collected about the person. As you shake hands with a previous contact, your PDA could cue you, through a tiny earpiece, with the business affiliation of the other person, as well as relevant personal information.rnAll this seems to be very interesting to read but is it practically possible to create a network of this sort? The answer is "YES" and the main aim of presenting this paper is to let the people know more about this technology and give them the knowledge about the technology used in PAN.
