Experimental Demonstration of Coupled Differential Oscillator Networks for Versatile Applications
(Frontiers Media SA, 2023)
Oscillatory neural networks (ONNs) exhibit a high potential for energy-efficient computing. In ONNs, neurons are implemented with oscillators and synapses with resistive and/or capacitive coupling between pairs of oscillators. ...

Scattering of Metal Colloids by a Circular Post under Electric Fields
(MDPI, 2023)
We consider the scattering of metal colloids in aqueous solutions by an insulating circular post under the action of an AC electric field. We analyze the effects on the particle of several forces of electrical origin: the ...

On-Line Evaluation and Monitoring of Security Features of an RO-Based PUF/TRNG for IoT Devices
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
The proliferation of devices for the Internet of Things (IoT) and their implication in many activities of our lives have led to a considerable increase in concern about the security of these devices, posing a double challenge ...

Compact Functional Testing for Neuromorphic Computing Circuits
(Institute of Electrical and Electronics Engineers Inc., 2023-07-01)
We address the problem of testing artificial intelligence (AI) hardware accelerators implementing spiking neural networks (SNNs). We define a metric to quickly rank available samples for training and testing based on their ...

Effect of Epsilon-Near-Zero Modes on the Casimir Interaction between Ultrathin Films
(American Physical Society, 2023)
Vacuum fluctuation-induced interactions between macroscopic metallic objects result in an attractive force between them, a phenomenon known as the Casimir effect. This force is the result of both plasmonic and photonic ...

Application of a Capacitively-loaded Split-ring Metamaterial Lens in a 0.3 T Magnetic Resonance Imaging System
(Elsevier, 2023)
In this work, it is demonstrated that metamaterial lenses can help to increase the signal-to-noise ratio of magnetic resonance imaging coils in low-field magnetic resonance imaging systems. In low-field magnetic resonance ...

Low-frequency electrokinetics in a periodic pillar array for particle separation
(Elsevier, 2023)
Deterministic Lateral Displacement (DLD) exploits periodic arrays of pillars inside microfluidic channels for high-precision sorting of micro- and nano-particles. Previously we demonstrated how DLD separation can be ...

Dynamics of Fixed-volume Pinned Films - Dealing with a Non-self-adjoint Thin-film Problem
(Cambridge University Press, 2023)
The use of thin liquid films has expanded beyond lubrication and coatings, and into applications in actuators and adaptive optical elements. In contrast to their predecessors, whose dynamics can be typically captured by ...

A Lightweight Remote Attestation Using PUFs and Hash-based Signatures for Low-end IoT Devices
(Elsevier, 2023)
Remote attestation is a powerful mechanism that allows a verifier to know if the hardware of an IoT (Internet-of-Thing) device (acting as a prover) has been counterfeited or tampered with and if its firmware has been ...

A 4.2–13.2 V, on-chip, regulated, DC–DC converter in a standard 1.8V/3.3V CMOS process
(Elsevier, 2023)
This paper presents a fully on-chip HV-regulated DC–DC boost converter for the power management unit of an electrical neural stimulator. The core of the DC–DC converter consists of a 4x4 array of individually-configurable ...
