A silver-nano electronic-ink print heating element separation-type electric thermotherapy apparatus includes two or more silver-nano electronic-ink print heating elements that emit heat using a power source applied from a power source unit. The electric thermotherapy apparatus includes a control unit which receives the power source from the power source unit to output a power source on-off signal and a temperature control signal for controlling the two or more silver-nano electronic-ink print heating elements, and the silver-nano electronic-ink print heating elements emitting heat depending on the power source and/or a temperature applied using the control unit, whereby an integral heating element, such as an electric mat, an electric mattress, an electric cushion, a hot-water mat, and an electric carpet, includes two or more divided parts, and thus it is easy to separately use the parts of the heating element and to independently control the temperature for the heating parts.

Wireless power transmission to inexpensive and disposable smart electronic devices is one of the key issues for the realization of a ubiquitous society where sensor networks such as RFID tags, price tags, smart logos, signage and sensors could be fully interconnected and utilized by DC power of less than 0.3W. This DC power can be provided by inductively coupled AC from a 13.56MHz power transmitter through a rectenna, consisting of an antenna, a diode and a capacitor, which would be cheap to integrate with inexpensive smart electronic devices. To integrate the rectenna with a minimum cost, a roll-to-roll (R2R) gravure printing process has been considered to print the rectenna on plastic foils. In this paper, R2R gravure printing systems including printing condition and four different nanoparticle based inks will be reported to print the rectenna (antenna, diode and capacitor) on plastic foils at a printing speed of 8mmin 1 and more than 90% device yield for a wireless power transmission of 0.3W using a standard 13.56MHz power transmitter. © 2012 IOP Publishing Ltd.

Since D flip-flop is one of the indispensable building blocks in integrated circuit (IC) design, providing a successful way to print D flip-flop on plastic foils will be the first step to reach fully printed flexible IC. Here, the network structure of single-walled carbon nanotubes (SWNTs) as an active layer has been employed to print the driver and load thin-film transistors (TFTs) of the D flip-flop. The same physical dimensions of driver and load TFTs were first developed to fully gravure print the D flip-flop because of the advantage of tunable electrical properties of network density of SWNTs. Therefore, the circuit design and printing becomes simpler and more convenient than using general design rules. Furthermore, the SWNT network structure in the active layer can also minimize the fluctuation of threshold voltages (Vth) of SWNT-TFTs because of the use of the same physical dimensions in TFTs. The resulting gravure-printed D flip-flop shows a clock-to-output delay of 23 ms for 20-Hz clock signal. This is the first reported D flip-flop performance using all gravure-printing method yet achieved. © 2011 IEEE.

A single-walled carbon nanotube (SWNT)-based 1-b full-adder circuit was realized on flexible plastic substrates through an all gravure printing process by minimizing intertransistor process variation and leakage current between crossing interconnects. The circuit comprised 27 printed SWNT thin-film transistors, with a variation of up to only ± 25% in electrical characteristics among them. Furthermore, the circuit showed a maximum propagation delay of 13.7 ms, with a 50-Hz input signal, and a supply voltage of-20 V. The process could be used for low-cost flexible arithmetic logic units in a variety of applications. © 2012 IEEE.
