Proof of Concept: a co-word analysis Proof of Concept: a co-word analysis
No full textThis study describes the conceptual structure of Proof of Concept (PoC) research in the fields of innovation and technology management over the past 33 years (1992-2024). Throughout this period, numerous terms and theoretical perspectives have emerged, leading to a fragmented and dispersed field. Utilizing a co-word analysis based on author keywords from the Scopus database, we selected the most frequent terms to provide a comprehensive overview of current studies. Through cluster analysis, we identify and highlight the key labels used by scholars to investigate PoC, illustrating their arrangement into distinct subgroups. Additionally, we interpret the relationships among terms using multidimensional scaling and employ overlay visualization to anchor the relevance of keywords over time. Our findings reveal the coexistence of several conceptualizations within PoC research, ranging from technological advancements to methodological approaches. This study offers a refined conceptual framework, contributing to both theoretical inquiry and practical applications in organizational contexts

Photovoltaic Energy Harvester with Power Management System
No full textWe present a photovoltaic energy harvester, realized in 0.35-μm CMOS technology. The proposed system collects light energy from the environment, by means of 2-mm2on-chip integrated microsolar cells, and accumulates it in an external capacitor. While the capacitor is charging, the load is disconnected. When the energy in the external capacitor is enough to operate the load for a predefined time slot, the load is connected to the capacitor by a power management circuit. The choice of the value of the capacitance determines the operating time slot for the load. The proposed solution is suitable for discrete-time-regime applications, such as sensor network nodes, or, in general, systems that require power supply periodically for short time slots. The power management circuit includes a charge pump, a comparator, a level shifter, and a linear voltage regulator. The whole system has been extensively simulated, integrated, and experimentally characterized.</jats:p
