Force‐Triggered Non‐Volatile Multilevel Mechano‐Optical Memory System for Logic Computation and Image Recognition

open access: yesAdvanced Science, EarlyView.
The integration of photostimulated luminescence with self‐recoverable mechanoluminescence materials endows the system with the capability to record and visually interpret mechanical information, concurrently exhibiting a six‐level non‐volatile memory architecture. This configuration showcases superior multi‐level and non‐volatile responses, which serve

Anti‐Motion Artifacts Iontronic Sensor for Long‐Term Accurate Fingertip Pulse Monitoring

open access: yesAdvanced Science, EarlyView.
Flexible pressure sensors are essential for pulse monitoring and cardiovascular disease diagnosis but are affected by motion artifacts (MAs) due to stretching stress. The S‐smooth sensor with a soft‐hard stretchable interface that dissipates energy, reducing MAs by 90% is developed.

PTAA‐Based Perovskite Photovoltaics Catching up: Ionic Liquid Engineering‐Assisted Crystallization Through Sequential Deposition

open access: yesAdvanced Science, EarlyView.
In the investigation, they introduce the ionic liquid 1‐ethyl‐3‐methylimidazolium formate (EMIMCOOH) into the lead iodide (PbI2) precursor solution, resulting in a mesoporous PbI2 film with larger pore sizes, which enhanced the conversion of PbI2 into perovskite material.

Simultaneous Harvesting of Bipolar Plasmonic Hot Carriers for Boosting Photoconductivity in Ag Nanoprism‐Coupled Lateral Si p–n Junction

open access: yesAdvanced Science, EarlyView.
This study demonstrates a plasmonic hot carrier device capable of extracting both types of hot carriers simultaneously using a lateral Si p–n junction diode coupled to Ag nanoprisms. The experimental and numerical results jointly reveal precise control of the generation and injection of plasmonic hot carriers, stemming from differing injection ...
