Amorphous oxide semiconductors (AOS) are a key material for future electronics because of their high mobility, excellent film quality even when layered at room temperature, and low fabrication cost. The AOS provides transparency because of its wide band-gap, allowing the development of transparent systems. This talk will review the mechanisms underlying dark and light instability in oxide thin-film transistors.
Although this family of materials is optically transparent, the presence of oxygen deficiency defects, such as vacancies and interstitials, located at sub-gap states, and their ionization under illumination, leads to absorption of blue and green photons. At higher energies, we have the usual band-to-band absorption. In particular, the oxygen defects remain ionized even after illumination ceases, eluding to persistent photoconductivity, which can limit the frame-rate of active matrix imaging arrays. However, the persistence in photoconductivity can be overcome with a positive gate pulsing scheme to enable a realistic frame rate for sensor-embedded display for touch-free interaction.

The adoption of physical and chemical sensors in high growth markets, from consumer electronics to automotive and healthcare drove the exponential growth in volume from about 20 million in 2007 to more than 3.5 billion in 2012, driven by some key technologies such as MEMS-based accelerometers and gyroscopes.
Based on the trend analysis and forecasts of market research organizations, sensor demand is expected to grow from billions in 2012 to trillions within the next decade, driven by the emergence of sensor- based smart systems fusing computing, communication and sensing, which will enable new markets in retail, Fast Moving Consumer Goods (FMCG), Point-Of-Care (POC) diagnostics and disposable electronics.
When compared to earlier sensor technologies, which were characterized by long development cycles, requiring more than a decade for converting proof of concepts to volume production, the advent of innovative manufacturing and hybrid integration technologies allows a dramatic reduction in the time to market.
Sensor technology alone is not enough to enable smart systems embedded in everyday objects, as in the visions and expectations of the “Internet of Things” (IoT) and “Wearable electronics”. New and revolutionary concepts of ultra-thin and conformable electronics, sensors and photonics, enabled by Large-Area Electronics manufacturing capabilities, are uniquely positioned to accelerate and lead the penetration of smart sensors and systems into new markets.
In emerging sensor and sensor network technologies, the sensing element needs to provide sufficient Signal to Noise Ratio (SNR) when the concentration of a specific substance reaches the minimum detection limit, and information highly specific to the particular target to detect. Combining simple electronics to amplify the signal at the point of detection is critical for achieving sufficient levels of SNR. Designing and manufacturing these application-specific electronic building blocks by means of simplified and cost-effective manufacturing process flows, such as those enabled by printed electronics, aims to reduce the time to market and increase the customization possibilities. This will ultimately enable “on-demand” design and development of a smart sensor unit into a truly flexible and conformable form factor.
Examples of programs and state-of-the-art developments in the field of smart sensors and systems will be described in the talk, highlighting the opportunity offered by Large-Area Electronics manufacturing and the challenges and limitations of conventional System-on-Chip (SoC) and System-in-Package (SiP) integration approaches, faced by today MEMS devices.

CMOS is at the heart of modern computing and communications technology. However, it is possible to think of the technology for making CMOS microelectronics as a material system with far more diverse possibilities. In this talk I will present results on the hybridisation of CMOS and nanotechnology for a range of sensor applications. These will include ion sensing for chemical and biological imaging and the all electronic next generation sequencing system. I will then explore the possibilities for hyperspectral and terahertz imaging based on the integration plasmonics and metatmaterial structures on CMOS.

Integrated electrochemical Nano-Bio-Sensors  for diagnosis and/or treatment of patients with specific physiological conditions (e.g., heart, cardiovascular, cancer diseases) or convalescents is a key factor to provide better, more rationale, effective and ultimately low-cost health care also at home. The ultimate goal of improved health care on those subjects is the extension of the patients’ autonomy, the possibility for auto-monitoring, the improvement of their comfort levels and their integration into everyday life. Some systems for on-line monitoring are available in the market. They use wearable devices (accelerometers, heartbeat monitoring system, etc). However, all these systems do not measure the human metabolism at molecular level (metabolites). The only available real-time, implantable/wearable systems for metabolic control are limited to glucose monitoring and used only for diabetic patients. However, electrochemical sensors may address so many other molecules, which have crucial relevance in human metabolism in chronic patients. So far, there are no available integrated nano-bio-systems for multi-metabolites, real-time, remote monitoring of the human metabolism. Thus, the aim of this plenary talk is to present an innovative concept for multi-panel, highly integrated, fully implantable, remotely powered and real-time monitoring systems for human metabolism at molecular level. The considered metabolic molecules will be glucose, lactate, glutamate, ATP , and anticancer drugs as well as anti-inflammatory ones . In case of drugs, the specificity of electrochemical sensors is improved at system level . The proposed nanotechnology will be based on carbon nanotubes to improve the sensors performance [3, 5]. To pursue their detection, innovative VLSI solutions  are discussed including the system remote powering . The new approach is obtained by integrating nano/bio/micro/CMOS/SW/RF systems in three devices: (i) a fully implantable sensors array for data acquisition; (ii) a on-skin intelligent-patch for remote powering and signal processing; (iii) a wearable station (a mobile phone) for data collection, elaboration and storage. The major presented breakthroughs are in the areas of: (i) nano-sensors; (ii) signal analysis; (iii) HW/Bio co-design; (iv) multi-panel metabolites detection; (v) fully implantable sensors; (vi) remote powering; (vi) minimally-invasive biomedical implants. System validation with in-vivo experiments on animal models is presented too  including packaging issues .
