on the naturalness, inevitability, and sense of security conveyed by touching in everyday life, this paper describes human area networking technology that enables communication by touching, called RedTacton. Here, the human body acts as a transmission medium supporting half-duplex communication at 10Mbit/s. The key component of the transceiver is an electric-field sensor implemented with an electro optic crystal and laser light. The human body shunts most of this electricity to the ground, resulting in a weak electric field that can be modulated to carry signals. The receiver is located either on another part of the body - a component of a hands-free headset or in an acquaintance's PDA. As it senses modulations in the electric field, the receiver decodes them to recover the data. 2. Introduction : Today people can communicate anytime, anywhere, and with anyone over a cellular phone network. Moreover, the internet lets people download immense quantities of data from remotely located servers to their home computers. Essentially, these two technologies enable communications between terminals located at a distance from each other. Meanwhile, all kinds of electronic devices including Personal Digital Assistants (PDAs), pocket video games, and digital cameras had became smaller, so everyone can carry around or even wear various personal information and communication appliances during their everyday activities. However, user-friendly ubiquitous services involve more than just networking between remotely located terminals. Communication between electronic devices on the human body (wearable computers) and ones embedded in our everyday environments such as illustrated in Fig. 1 is also critical, so this has driven extensive research and development on human area networks. Wired connections between electronic devices in human area networks are cumbersome and can easily become entangled. Short-range wireless communication systems such as Bluetooth and wireless Local Area Networks have some problems. Throughput is reduced by packet 3

collisions in crowded spaces such as meeting rooms and auditoriums filled with people and communication is not secure because signals can be intercepted.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
