K+‐Triggered Defect Engineering and Proton‐Coupled Storage in V2O5·nH2O for Advanced Zn‐Ion Thin‐Film and Microbatteries

Advanced Science, EarlyView.
K+ pre‐intercalation in V2O5·nH2O induces interlayer contraction, oxygen‐vacancy formation, and mixed‐valence states, activating defect‐mediated proton‐dominated transport. This enables cooperative H+/Zn2+ storage with enhanced kinetics and stability. The resulting Zn‐based thin‐film and microbatteries deliver high areal energy and capacity, offering a

A Folded, Structure‐Integrated Bimodal Sensor Enabling Non‐Contact and Tactile Perception for Intelligent Robots

Advanced Science, EarlyView.
A foldable bimodal sensor integrates a triboelectric nanogenerator and graphene piezoresistive effect into a monolithic laser‐induced graphene film. It enables synchronous non‐contact and tactile perception, achieving a distance of 110 mm, a sensitivity of 11.2 kPa−1, and a response time of 10 ms.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

The capacitive sensor

2009 32nd International Spring Seminar on Electronics Technology, 2009
This paper is focused on a cavity in LTCC (Low Temperature Co-fired Ceramics), which is one of the methods used for creation of pressure sensor. The mechanical part is 3D structure in which there are integrated electrodes created by TFT (Thick Film Technology). One of them is fixed and the other one is on the deformation element.

Determination of the theoretical capacitance of a concave capacitance sensor

Review of Scientific Instruments, 1979
The practical use of four concave capacitance plates for determining in situ volume fractions in two-phase pipelines has been amply demonstrated. In this letter, the system is analyzed theoretically using a microstrip technique and the results are compared with experimental data.

Unique and Unclonable Capacitive Sensors

IEEE Sensors Journal, 2018
Inspired from nature, a new concept called 'sensors with unique and unclonable characteristic', has been developed. Such sensors respond to a measurand and provide a unique output. Random variations in the structure of the sensors are responsible for these unique characteristic.

An accurate interface for capacitive sensors

IEEE Transactions on Instrumentation and Measurement, 2002
A new smart interface based on a first-order charge-balanced SC-oscillator is presented for capacitive sensors, which are shunted by a parasitic conductance. In the novel interface, the effect of shunting conductance is reduced by using the charge/discharge method.
