Abstract A flexible full-color micro-LED display with high mechanical robustness was fabricated by printing quantum dots (QDs) on a blue array using standard photolithography. The red and green colors yielded from QDs exhibit better color gamut than conventional filters. light conversion efficiency enhanced adding TiO 2 nanoparticles to the QD-photoresist composite. This successfully mounted various unusual substrates such as curved glass, fabrics, human skin, enabling diverse optoelectronic...
Intracranial implants for diagnosis and treatment of brain diseases have been developed over the past few decades. However, platform conventional implantable devices still relies on invasive probes bulky sensors in conjunction with large-area craniotomy provides only limited biometric information. Here, an multi-modal sensor array that can be injected through a small hole skull inherently spread out conformal contact cortical surface is reported. The injectable array, composed graphene...
The demand for wearable electronics in the fields of human healthcare monitoring and disease diagnosis has significantly increased recent years. In particular, there is a need light-weight, skin-friendly, soft elastic devices that can attach comfortably to skin communicate information via Internet Things. Rigorous research been carried out find new materials device designs meet challenging demands skin-mountable devices. emergence atomically thin two-dimensional (2D) with exceptional...
The uniform deposition of perovskite light-emitting diodes (PeLEDs) and their integration with backplane thin-film transistors (TFTs) remain challenging for large-area display applications. Herein, an active-matrix PeLED fabricated via the heterogeneous cesium lead bromide LEDs molybdenum disulfide (MoS
Advancements in the synthesis of large-area, high-quality two-dimensional transition metal dichalcogenides such as MoS2 play a crucial role development future electronic and optoelectronic devices. The presence defects formed by sulfur vacancies results low photoluminescence emission imparts high n-type doping behavior, thus substantially affecting material quality. Herein, we report new method which single-phase (liquid) precursors are used for metal–organic chemical vapor deposition...
Injectable 2D Material-Based Sensor Array Jong-Hyun Ahn and co-workers have developed an implantable sensor array for diagnosing treating brain diseases. This can be injected through a small hole in the skull, providing conformal contact with cortical surface. Composed of graphene electrodes MoS2-based sensors, it record neural activity, stimulate electrically, monitor intracranial temperature pressure. More details found article number 2400261.
