In this work, uniform and highly aligned ZnO nanorod arrays were simply synthesized on zinc plates by hydrothermal method using zinc–ammonia complex solution. Effects of seed layer formation, Zn(NO3)2 concentration NH3/Zn(NO3)2 mole ratio (R) in the reaction medium morphology crystal structure nanorods investigated detail. grown surfaces crystalline had a hexagonal wurtzite structure, as revealed XRD analysis. addition, dominant growth direction was c-axis, indicating verticality nanorods. SEM images showed that one-dimensional (1D) with high number density seeded whereas randomly oriented non-seeded surfaces. Increase Zn2+ changed top ends rods from tapering to ends; also led an increase average size The R value (or i.e., amount NH3) caused misalign surface decrease size. well-aligned can be adjusted 50 260 nm diameter 0.11 6 m length changing parameters, implying their large potential used photocatalytic electronic applications.

Piezoelectric semiconductors have emerged as a prominent area of research in recent years due to their unique combination piezoelectric and semiconductor properties. In this Letter, we propose device structure featuring coplanar electrodes positioned above the layer. We conducted detailed theoretical analysis properties device. By utilizing electrode mode, pressure applied one generates potential difference between two electrodes. Notably, performance can be adjusted by modifying its structure. Numerical simulations experimental results indicate that reaches an optimal value when distance is equal one-half length. Additionally, developed method enhance voltage output capability under low load resistance conditions. Specifically, introducing charge carriers into layer from doped silicon substrate, device's reduced Schottky contact. The operating mode proposed paper facilitates energy harvesting self-powered sensing, distinguishing it d31 d33 operational modes associated with traditional sandwich structures, thereby allowing for more versatile configurations.

An artificial algorithm using a machine learning approach could be used to determine the energy band gap, E g which would simply process of synthesizing ZnO properties. This paper proposes develop models that can accurately predict gap ZnO. study PSO-SVR model utilizing three kernel functions: linear, polynomial, and RBF. The with RBF resulted in lowest RMSE 0.0395eV. analysis also showed combination lattice constant c , crystallite size, D grain size datasets had contributed high accuracy predicting .

Electronic skin (E-skin) refers to a portable medical or health electronic device that can be worn directly on the human body and carry out perception, recording, analysis, regulation, intervention even treatment of diseases maintenance status through software support. Its main features include wearability, real-time monitoring, convenience, etc. E-skin is convenient for users wear long time continuously monitors user’s physiological data (such as heart rate, blood pressure, glucose, etc.) in real time. Health monitoring performed anytime anywhere without frequent visits hospitals clinics. integrates multiple sensors intelligent algorithms automatically analyze provide advice early warning. It has broad application prospects field. With increasing demand E-skin, development multifunctional integrated with low power consumption autonomous energy become common goal many researchers. This paper outlines latest progress disease treatment, human–computer interaction other fields. The existing problems this field are presented.
