From Springer description: "We present the design considerations of an autonomous wireless sensor and discuss the fabrication and testing of the various components including the energy harvester, the active sensing devices and the power management and sensor interface circuits. A common materials platform, namely, nanowires, enables us to fabricate state-of-the-art components at reduced volume and show chemical sensing within the available energy budget. We demonstrate a photovoltaic mini-module made of silicon nanowire solar cells, each of 0.5 mm2 area, which delivers a power of 260 μW and an open circuit voltage of 2 V at one sun illumination. Using nanowire platforms two sensing applications are presented. Combining functionalised suspended Si nanowires with a novel microfluidic fluid delivery system, fully integrated microfluidic–sensor devices are examined as sensors for streptavidin and pH, whereas, using a microchip modified with Pd nanowires provides a power efficient and fast early hydrogen gas detection method. Finally, an ultra-low power, efficient solar energy harvesting and sensing microsystem augmented with a 6 mAh rechargeable battery allows for less than 20 μW power consumption and 425 h sensor operation even without energy harvesting."

DOCUMENT
The revolutionary dimension of technological developments is all too often placed in the foreground, painting a picture of a future we can hardly imagine, let alone perceive. This book emphasises the evolutionary dimension of developments, and how we take small steps. How certain underlying, invariable aspects survive hype after hype, and have their own rhythm or longue durée. It is the search for where change meets inertia. Progression is a balance between the familiar and the unfamiliar. The essays bundled in this book have as a leitmotiv this attention to how progression is a matter of locating the small steps we can take and the invariables that lie beneath developments that stimulate or hinder certain big steps forward. It concentrates on the zone of proximal development, to use the term of Vygotsky. This collection of essays represents a personal view of the area where psychology, media, technology, and culture meet in the context of technological and social developments. These crossroads are addressed through topics such as digital identities, interactive media, the museum visitor in a digital world, and growing up in a digital society.
