Developing Implantable High‐Sensitivity Piezoelectric Thin‐Film Sensor to Monitor Partial Discharge of Generator Stator Windings

open access: yesHigh Voltage, EarlyView.
ABSTRACT Insulation failures resulting from partial discharges (PD) in generator stator windings represent a leading cause of generator breakdowns. Conventional acoustic emission sensors for detecting PD ultrasonic signals are typically made from bulky piezoelectric materials and are restricted to external placement on the generator.

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

open access: yesHigh Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films

open access: yesAdvanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

Charge Injection for Polarization Screening at Electrode Interfaces and the Antiferroelectric Double Hysteresis Loop of La‐Doped Pb(Zr,Sn,Ti)O3

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Screening of the bound polarization charges of ferroelectrics at electrode interfaces is accommodated either by electrode charges or by charge injection. By means of X‐ray photoelectron spectroscopy with in‐situ polarization reversal, it is demonstrated that screening charges at antiferroelectric La‐doped Pb(Zr,Ti)O3 are injected, while they remain at ...
