Mimicking Synaptic Plasticity: Optoionic MoS2 Memory Powered by Biopolymer Hydrogels as a Dynamic Cations Reservoir

Advanced Functional Materials, EarlyView.
Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

An Improved Recursive ARIMA Method with Recurrent Process for Remaining Useful Life Estimation of Bearings

Shock and Vibration, 2022
A typical way to predict the remaining useful life (RUL) of bearings is to predict certain health indicators (HIs) according to the historical HI series and forecast the end of life (EOL).

Securing Internet of Things with Lightweight IPsec [PDF]

, 2010
Real-world deployments of wireless sensor networks (WSNs) require secure communication. It is important that a receiver is able to verify that sensor data was generated by trusted nodes. In some cases it may also be necessary to encrypt sensor data in

Internet of Things or Surveillance of Things?

, 2018
The paper deals with digital surveillance in the postmodern world. We define a new term ‘Surveillance of Things’ in the context of the study of the surveillance, and try to determine, whether and how the surveillance of people is connected with surveillance of things.

Everything-as-a-Thing for Abstracting the Internet-of-Things

Proceedings of the 13th International Conference on Software Technologies, 2018
This paper discusses Everything-as-a-Thing (*aaT) as a novel way for abstracting the Internet-of-Things (IoT) applications. Compared to other forms of abstraction like Everything-as-a-Service (*aaS) and Everything-as-a-Resource (*aaR), *aaT puts emphasis on living things, on top of non-living things, that populate these applications.

Gated PN Junction in Ambipolar MoS2 for Superior Self‐Powered Photodetection

Advanced Functional Materials, EarlyView.
A high‐quality gated pn junction based on ambipolar molybdenum disulfide (MoS2) is demonstrated by employing a partial‐gate structure and a Pt bottom contact that forms a semi‐van der Waals interface, facilitating efficient hole injection into the channel.

Selective and Precise Editing of Digital Polymers Through Parallel or Series Toehold‐Mediated Strand Displacement

Advanced Functional Materials, EarlyView.
A sequence‐encoded supramolecular construct containing two accessible toeholds is developed herein for enabling multiple editing operations. By introducing specific input strands, it is possible to selectively erase or rewrite digital content through parallel or series toehold‐mediated strand displacement (PTMSD or STMSD).

Label‐Free and Low‐Power Driven Cancer Biomarker Detection Enabled by 2D Hexagonal Titanium Oxide

Advanced Functional Materials, EarlyView.
A low‐power driven FET biosensor based on 2D hexagonal TiO2 detects the cancer biomarker carcinoembryonic antigen with high sensitivity, a low detection limit of 0.22 pg mL−1, and excellent selectivity. Leveraging the unique electronic properties of the material, this work demonstrates strong potential for integration into miniature and portable cancer

Near‐Sensor Analog Computing via Monolithic 3D Piezoelectric Sensor–FeFET for Tactile Sensing System

Advanced Functional Materials, EarlyView.
A monolithic 3D‐integrated tactile system combines a piezoelectric sensor and ferroelectric field‐effect transistor (FeFET) to process both static and dynamic pressure signals directly at the sensor node. The system enables in‐sensor analog noise filtering with multi‐level memory states, achieving high sensitivity and ultra‐low power operation (≈10 nW),
