This paper reviews several examples of ultra low power sensor interfaces for IoT applications. In such applications, the sensing operation is often performed at a relatively low frequency, and sometimes it is heavily duty-cycled, or it should be triggered by particular events or thresholds. The paper reviews why dynamic sensor interface architectures are a good choice in this context, and gives several design examples that can operate dynamically and that can be triggered by a single clock pulse. Suitable ADC design strategies are explained, and two exemplary sensor interfaces are described: a capacitive sensor interface, and a resistor-based temperature sensor interface including analog correction techniques. Both designs are reviewed and the main features in terms of efficiency and performance are discussed.

Sensing systems are present in most application domains, including those in harsh environments. These systems are often designed around processing units sensitive to these environmental conditions. Still, the systems must withstand extreme operational conditions in these environments and maintain consistent measurements. In this work, we present the challenges imposed by radiation effects in sensing applications and discuss the utilization of a fault-tolerant RISC-V System-on-Chip, the HARV-SoC, to mitigate their impact. The HARV-SoC comprises peripherals and the fault-tolerant HARV core, which relies on hardening strategies, such as physical and information redundancy, to meet the requirements of critical applications targeting harsh environments and reduce the propagation of errors. Hence, we guide how to employ the proposed system in sensing applications and empower the community with a new tool for reliability-oriented projects.

We present the characterization of the new Frontend Electronics (FEE) developed for the Schwarzschild-Couder Telescope (SCT) camera of the CTA experiment. The new FEE is based on a new Application-Specific Integrated Circuit (ASIC) intended to read-out arrays of Silicon Photomultipliers (SiPMs) for low-level light detection down to the single photoelectron, called SMART (SiPM Multichannel ASIC for high Resolution Cherenkov Telescopes). The analog channel is composed of a high speed path with programmable gain and pole-zero filter designed for photon-counting. An external fast digitizer can be used for the photon-counting analysis. A slow path allows the measurement of the mean SiPM current, sampled by an internal 10-bit ADC. We present the characterization results obtained when coupling the SMART to a 16 SiPM matrix produced by Fondazione Bruno Kessler (FBK). Results in terms of charge spectrum, signal-to-noise ratio and dynamic range will be presented. The SMART ASIC was then coupled to the SCT readout electronics based on the TARGET ASICs, able to digitize waveforms at a frequency of 1GS/s and to generate trigger signals. In this work, we further present the preliminary characterization obtained on the full FEE chain.
本文介绍了用于CTA实验的史瓦西- couder望远镜(SCT)相机的新型前端电子器件(FEE)的特性。新的FEE基于一种新的专用集成电路(ASIC)，旨在读出硅光电倍增管(SiPMs)阵列，用于低强度光探测，直到单个光电子，称为SMART(用于高分辨率切伦科夫望远镜的SiPM多通道ASIC)。模拟通道由高速可编程增益路径和用于光子计数的极零滤波器组成。外部快速数字化仪可用于光子计数分析。慢路径允许测量平均SiPM电流，由内部10位ADC采样。我们展示了将SMART与Fondazione Bruno Kessler (FBK)生产的16 SiPM矩阵耦合时获得的表征结果。将给出电荷谱、信噪比和动态范围方面的结果。然后，SMART ASIC与基于TARGET ASIC的SCT读出电子器件耦合，能够以1GS/s的频率数字化波形并产生触发信号。在这项工作中，我们进一步介绍了在整个FEE链上获得的初步表征。

The concept behind Internet of Things (IoT) involves connecting physical objects to the internet and endowing them with the ability to identify one another and exchange data. This communication paradigm arises new security challenges. Mainly, authenticity of network nodes, to let ones with malicious intent not thrive in such a network; and confidentiality, when sensitive data have to be exchanged. Most classical security techniques are not suitable to address such issues, especially in Wireless Sensor Network (WSN) where network nodes are developed using resource-constrained devices. Consequently, the scientific literature has been starting to investigate how Physically Unclonable Functions (PUFs), a unique digital identifier obtained from physical variability induced by integrated circuit manufacturing process, could be exploited to provide security mechanisms. In this paper, we present ConPHEMAP, a new lightweight PUF-based key management-scheme for point-to-point communications. The proposed scheme extends the PHEMAP protocol and inherits same properties, including flexibility since can be adopted either in the case where both nodes are provided with PUFs or when only one of them includes it. We also conducted a security analysis to verify the protocol resilience against different kinds of attacks, which proves its suitability in a heterogeneous insecure context such as WSNs.

Lab-on-Chip technology is gaining great interest due to the many possibilities that it offers in the fields of life sciences, from parallel analysis in genomics to point-of-care devices in medical diagnostics. At the beginning, Lab-on-Chip devices essentially consisted of a microfluidic network that miniaturized the analytical procedures leading to faster reaction kinetics and lower sample and reagents consumption. Recent devices integrate several functional modules, that allow all the functions of a human-scale test laboratory including transferring samples, drawing off a precise volume of a chemical product, reagent mixing, DNA extraction, detection and quantification of biomolecules.

In this work, we propose an analog fully differential interface for capacitive sensors. The working principle of the proposed solution is based on an auto-balancing bridge topology entirely formed by capacitive components. In particular, two capacitors form the sensor, while other components are voltage-controlled capacitors (VCCs) which in steady-state conditions follow sensor capacitor values through a negative feedback performing the zero-convergence of the differential output at the bridge. Theoretical curves involving VCCs control voltages have been extracted and compared with experimental values on a discrete component printed circuit board (PCB), showing very good agreement. The effect of parasitic capacitances have been also considered from evaluations on the PCB, obtaining that their contribution increases if the reference baseline capacitance of the auto-balanced bridge decreases. This study opens to further investigations about modeling and compensation of these capacitance sensors.

Wind turbines have played a significant role in the transition toward renewable energy sources. Accurately determining the position and motion of the rotor blades has emerged as a crucial feature for advancing their adoption and widespread use. The problem addressed in this paper is the use of a single low-power and cost-effective Inertial Measurement Unit (IMU) mounted on a wind turbine blade for position and motion estimation. Standard attitude algorithms can be used to estimate the position of a sensor relative to the earth’s frame. However, they cannot extract information about additional blade features, such as the pitch angle or the occurrence of flap-wise deflections. This paper establishes a novel framework that facilitates the identification and estimation of dynamic wind turbine angles by defining appropriate reference frames. Experimentally acquired IMU data is used to extract rotation matrices that establish the relationship between reference frames. Experimental results show the possibility of estimating the blade orientation, deflection, and twist with a $approx 1^{circ}$ precision, in addition to the relative blade altitude with an error of 5 mm.
