Abstract:
We present a survey on battery-less Radio Frequency Identification (RFID-based wireless sensors that have emerged in the past several years. We discuss the evolution of RFID turning into wireless sensors. Moreover, we talk about different components of these battery-less RFID-based wireless sensors, five main topologies that transform a simple RFID chip into a battery-less wireless sensor, and state-of-the-art implementations of these topologies. In battery-less wireless sensors, the read range is of key importance. Hence, we discuss how each component of the sensor plays its role in determini

Abstract:
A ruthenium oxide (RuOx) sensor for potentiometric pH sensing is currently being developed for organs-on-chip purposes. The sensor was fabricated from a Ru(OH)3 precursor, resulting in RuOx nanorods after heating. An open-circuit potential of the RuOx electrode showed a near-Nernstian response of −58.05 mV/pH, with good selectivity against potentially interfering ions (lithium, sulfate, chloride, and calcium ions). The preconditioned electrode (stored in liquid) had a long-term drift of −0.8 mV/h, and its response rate was less than 2 s. Sensitivity to oxygen was observed at an order of magnit

As an important means to protect water resources, water quality detection is of great social and economic significance. Water quality detection sensors processed by micro-electro-mechanical system (MEMS) technology have the advantages of low-cost, small size, and high sensitivity. In this paper, a multi-parameter water quality detection integrated sensor chip is further studied, and a portable detection system using this chip is developed. Temperature, pH, oxidation-reduction potential (ORP), conductivity and concentration of copper ions (Cu2+) are selected as typical water quality parameters.

We review the recent advances in the use of our originally developed on-chip graphene aptasensor to detect biologically important proteins, such as cancer markers. The detection mechanism, based on fluorescence resonance energy transfer (FRET), occurs at a graphene–biomolecule interface. In our system, the graphene surface is modified with a pyrene–aptamer–dye probe. Pyrene functions as a linker to the graphene surface, the aptamer as a probe for selective protein recognition, and the dye as a fluorescence detection tag. Here, graphene behaves simultaneously as both an efficient acceptor for F

Distributed Algorithm (DA) has been applied widely because it doesn’t need multiply operation. The serial structure DA takes less chip resource but more calculation time, while the full pipeline parallel structure DA is just the reverse. A Serial-Parallel combined DA is proposed in this paper to take full advantages of the above structures to realize sampled data filter from sensor signal. Through the verification by simulation and synthesization, it is shown that the proposed improved serial-parallel DA can realize real time high speed sampled data filter from sensor, and it can reach the bes

This book confronts the hotly debated prospect of mounting job losses from automation, and the divergent hopes and fears that prospect evokes, and proposes a strategy for mitigating the losses and spreading the gains from shrinking demand for human labor.

As ongoing innovations in artificial intelligence, machine learning, and robotics continue to chip away at the comparative advantages of human labor in a range of work tasks, those innovations a

Abstract:
In the context of multi-IP chips making use of internal communication paths other than the traditional buses, source synchronous links for use in multi-synchronous Networks-on-Chip (NoCs) are becoming the most vulnerable points for correct network operation and therefore need to be safeguarded against intra-link delay variations and signal misalignments. The intricacy of matching link net attributes during placement and routing and the growing role of process parameter variations in nanoscale silicon technologies, as well as the deterioration due to the ageing of the chip, are the root causes for this. This chapter addresses the challenge of designing a timing variation and layout mismatch tolerant link for synchronizer-based GALS NoCs by implementing a self-calibration mechanism. A timing variation detector senses the misalignment, due to process variation and wearout, between data lines with themselves and with the transmitter clock routed with data in source synchronous links. Then, a suitable delayed replica of the transmitter clock is selected for safe sampling of misaligned data. This chapter proves the robustness of the link in isolation with respect to a detector-less link, also addressing integration issues with the downstream synchronizer and switch architecture, proving the benefits in a realistic experimental setting for cost-effective NoCs.

Five gauges were aligned at a interval of 20-μm between the bumps.
