“…Arduino is a microprocessor-based system with open-source hardware and software for signal processing and computation (see http://www.arduino.cc/ ). The Arduino platform has also demonstrated its utility for applications with flexible or wearable electronics [20] . The Arduino is capable of applying a step input to a resistor and capacitor in series and measuring the time required for the potential on the capacitor to reach 2 V (see an example at http://arduino.cc/it/Tutorial/CapacitanceMeter and the Supporting Information for code used in SI Video 1).…”

Table of Contents:Mazzeo et al. describe methods of patterning metallized paper to create touch pads of arrayed buttons that are sensitive to contact with both bare and gloved fingers. The paper-based keypad shown detects the change in capacitance associated with the touch of a finger to one of its buttons. Mounted to an alarmed cardboard box, the keypad requires the appropriate sequence of touches to disarm the system. Image for Table of Contents:Submitted to 2 This paper describes low-cost, thin, and pliable touch pads constructed from a commercially available, metallized paper commonly used as packaging material for beverages and book covers. The individual keys in the touch pads detect changes in capacitance or contact with fingers by using the effective capacitance of the human body and the electrical impedance across the tip of a finger. To create the individual keys, a laser cutter ablates lines through the film of evaporated aluminum on the metallized paper to pattern distinct, conductive regions. This work includes the experimental characterization of two types of capacitive buttons and illustrates their use with applications in a keypad with 10 individually addressable keys, a keypad that conforms to a cube, and a keypad on an alarmed cardboard box. With their easily arrayed keys, environmentally benign material, and low cost, the touch pads have the potential to contribute to future developments in disposable, flexible electronics, active, "smart" packaging, user interfaces for biomedical instrumentation, biomedical devices for the developing world, applications for monitoring animal and plant health, food and water quality, and disposable games (e.g., providers of content for consumer products).There is no simple method of integrating buttons with structures on single-use or throwaway devices. Current commercial buttons are not thin enough, inexpensive enough, or easy enough to array seamlessly with paper-based products for disposable applications. The touch pads in this work are thin (~60 µm in some cases), simple to array, fabricated by etching patterns into metallized paper, low-cost (< $0.25 m -2 for the thin grade of metallized paper we use in this work), and lightweight (100s of g m -2 ). The individual keys measure changes in capacitance when touched by a user, and the buttons require no physical displacement of conductive elements. Even though the individual keys on the touch pads detect changes in capacitance, the paper-based keypads are still functional when touched by fingers in nitrile gloves. Submitted to 3Developments in paper-based electronics include ring oscillators with organic electronics [1] , transistors [2][3][4] , methods for patterning conductive traces [5][6][7] , speakers [8] , super capacitors [9] , batteries [10] , MEMS [11] , and solar cells [12] . Each of these developments focuses on a single technological advance that would enable new types of consumer products. Many types of new consumer products will require some form of user interface or input. In order to gather ke...

“…The everyday presence of textile surfaces and its application to create soft, fabric-based computers embody Mark Weiser's vision of ubiquitous computing [13]: providing functionality while disappearing discreetly into the soft surface of the 'textiled' space. The esthetics, material qualities, and flexibility of the textiles present large possibility for embedded computation [4], or as a medium to form 'computational composite' [9] to create a pervasive, playful, and theatrical interactive experience for all.…”

This paper presents Felted Terrain, an interactive textile with embedded soft electronics, that creates a sensorial experience with tactility, sound, and esthetics. The project takes the traditional craft of knitting and applies computation at different points of processes, from pattern generation with parametric scripting to integration of conductive and flexible electronics for creating user interactivity. With digital design and fabrication tools, the sensor-embedded textile is produced to be experienced at the spatial level of the interior. The paper discusses the design processes of the project and the potentials of embedding unexpected interactivity to the everyday object of the knitted fabric to provide opportunities for multi-sensorial experiences.

“…Nodes of the network, mounted on different parts of the human body, exploit tri-axial accelerometers to detect body postures [6]. The disadvantages of that solution lies in the impracticality of wearing many sensors and purring daily life activities such as working or studying and the lack of feedback provided for users.…”

Abstract-To understand how good posture minimizes computer related injury's pain, we developed Postuino. A device that warns the computer users if they are leaning too close towards computer screen. Postuino has an accompanying web application that visualizes the collected data and displays a chart to simplify comparing between straight time and slouch time. Also, the app suggests taking frequent breaks to minimize the risk of injuries and to increase productivity. Then, we designed an experiment with different factors to evaluate the efficiency of Postuino. In our study, 24 subjects first use the computer for 3 hours after disabling Postuino's alert system. Afterwards, they use the computer again for two more 3 hour phases after enabling the alert system. We collected data, analyzed it, and presented the results in this paper.
