Electro-active nano-composite actuator based on fullerene-reinforced Nafion

An electro-active artificial muscle based on the fullerene-reinforced ionic polymer membrane was newly developed to overcome some of the drawbacks of traditional ionic polymer–metal composite actuators. Tensile strength and Young’s modulus more than doubled with addition of minute quantities of fullerenes. While the ion exchange capacity of the fullerene–Nafion membrane does not change appreciably, proton conductivity and water-uptake ratio that are the main factors for higher magnitude of actuation increased dramatically. The harmonic responses of the fullerene-reinforced ionic polymer actuators almost doubled and the frequency responses greatly improved in the low-frequency region. The straightening-back phenomenon of the fullerene-reinforced actuator was considerably reduced with the addition of fullerene nano-particles.

Smart card embedded information systems: a methodology for privacy oriented architectural design

The design of very small databases for smart cards and for portable embedded systems is deeply constrained by the peculiar features of the physical medium. Privacy concerns are relevant due to the fact that personal information may be stored on the card (e.g. medical records). We propose a joint approach to the logical and physical database design phases supporting the required security levels, on the basis that all information is stored on the Flash-EEPROM storage medium, managed as a file system by the smart card operating system.     

<Emphasis Type="Italic">Smart CAPs for Smart Its</Emphasis> – Context Detection for Mobile Users

Context detection for mobile users plays a major role for enabling novel, human-centric interfaces. For this, we introduce a context detection scheme applicable in a self-organized sensor network, which is formed of disseminated, computer empowered sensors, referred to as Smart-Its [1]. Context-detection takes place without requiring any central point of control, and supports push as well as pull modes. Our solution is based on an in-network composition approach relying on so-called smart Context-Aware Packets (sCAPs). These packets act as a uniform interchange format, and allow single sensors to share sensed data and to cooperate to build up a meaningful context model from manifold inputs. sCAPs travel through the sensor network governed by an enclosed retrieving plan, specifying which sensors to visit in order to gain a specific piece of context information. For enhanced flexibility, the retrieving plan itself may be dynamically altered in accordance with past sensor readings.
