The automotive electronics market has increased steadily over the past several years even at times when the automobile market per se is not growing substantially. Indeed the per car electronics content is increasing at a fast pace. This is just the tip of the iceberg as we are entering the age of the “zero-accident car” with autonomous driving based on wireless and wired networks of powerful sensors...
Wearable smart sensing is a promising technology to enhance user experience that has already been exploited in sport/fitness, as well as health and human monitoring. Wearable sensing systems not only provide continuous data monitoring and acquisition, but are also expected to process, and make sense of the acquired data by classification in similar ways as human experts do. Supporting continuous operation...
Cyber-physical systems (CPSs) embed HW/SW devices that implement controlling strategies of physical processes. Such strategies are usually designed as architecture agnostic mathematical models, that are unaware of constraints imposed by the embedded HW platform. As such, the developed strategy may be unable to control the actual system. This implies the need of cyber-physical virtual-platforms (VPs),...
In this paper we report the experimental results of lateral 4H-SiC UV p-i-n photodiodes, whose p-type anode and n-type cathode regions are made by Aluminum and Nitrogen, respectively, ion-implantation. The dark reverse current is −31.5pA at −10V and increases at −1.24nA under 320nm UV radiation with an optical power at the surface of the device equal to 7.5nW. The peak of the responsivity is 0.074A/W...
Due to the growing demand for humidity control systems, there is a need for small, cheap, accurate and reliable sensors for air relative humidity (RH) measurements. In this paper, a resonant air relative humidity sensor is presented. The sensor is based on a quartz crystal coated on both surfaces with a hygroscopic polymer. Due to the adsorption of water molecules, the polymer mass increases accordingly...
This paper presents the fabrication and testing of a lab-on-chip system suitable for treatment of DNA. It includes two main modules: a system-on-glass (SoG) and a disposable microfuidic chip. The SoG integrates, on the same glass substrate, thin film metal heaters and amorphous silicon temperature sensors to achieve a uniform temperature distribution (within ±1°C) in the heated area. Two polydimethylsiloxane...
In this paper, we report on the design, fabrication and characterization of a low cost, portable detection system able to quantify, in a rapid and reliable way, the contamination level of Ochratoxin A (OTA) in red wine. The operating principle is the real-time monitoring of the natural fluorescence of OTA molecules during a chromatographic run on a thin layer chromatographic plate. The fluorescence...
Recently, combination of genetic engineering and optical technology enables to measure and control biological functions with light. Fluorescent protein such as GFP can be used as an optical tag of a specific molecule, and photoactive protein such as ChR2 can be applied for optical manipulation of biological functions. This presentation introduces some kinds of implantable optical devices for measuring...
Essential tremor is the most common form of tremors presenting an outpatient neurology practice and yet it may be often difficult to differentiate with tremors in Parkinson's disease — one of the commonest neurodegenerative disease. Since using appropriate medication is fundamental for efficacy and avoiding serious side effects, precise diagnoses are recommended. Single photon emission computerized...
Imec has launched a virtual personal health coach research program which combines wearable technology and data sciences for providing new coaching methodologies towards managing an active lifestyle, managing stress, and smoking cessation, with the ambition to have a big impact on preventive health and reduce the future incidence of chronic disease. Chronic diseases currently account for 70 to 85%...
The Gabor filter has gained an important agreement in multimedia processing and visual search applications for its good spatial frequency and position selectivity, notwithstanding its heavy computational load. For these reasons, Gabor filters find useful applications in the processing of medical images, aiming to enhance the original image and to overcome issues related to noise and artifacts. With...
This paper presents a low temperature technological process ahle to integrate an all-glass microfluidic network with an ElectroWetting On Dielectric (EWOD) structure for the digital handling of liquids. The fluidic channels result from the wet-etching of the glass, while the electrodes necessary for the droplet movement are deposited on the bottom and top surfaces of the microfluidic structure. The...
This work is concerned with the development of a wireless low-power wearable system to be used for multi-lead ECG monitoring. Potential applications can range from sport and ñtness to healthcare. The paper aims to present the architecture of the system and its performance, along with in-vivo results achieved with carbon based smart textiles.
Capacitive sensors have important advantages and are widely used, but typically up to sensing distances comparable to sensor size. We present the design and experimental results of a self-contained long range capacitive sensor that is suitable for indoor human localization. We make differential measurements of the reactance effects of sensor plate capacitance using a constant excitation frequency,...
This paper presents an NPN-based temperature sensor intended for the temperature compensation of the metal shunt resistor of an integrated current sensing system. The sensor was implemented in a 0.18 HV BCD CMOS technology and occupies 0.16mm2 After a one-point trim, its inaccuracy is less than ±0.4°C over the industrial temperature range (−40°C to 85°C). It also achieves 14.8niK resolution in a 7ms...
Deep convolutional neural networks are being regarded today as an extremely effective and flexible approach for extracting actionable, high-level information from the wealth of raw data produced by a wide variety of sensory data sources. CNNs are however computationally demanding: today they typically run on GPU-accelerated compute servers or high-end embedded platforms. Industry and academia are...
With aggressive scaling of silicon technology, integrated circuits (ICs) yield has emerged as a prominent concern. Yield loss comes from timing problems induced by process variations introduced by inaccuracy in nano-scale CMOS fabrication. To address this concern, we have developed a system to assist in optimizing yield and power. The system consists of timing violation sensors, clock duty-cycle controllers,...
