Research on Output Characteristics of a Non-Contact Piezoelectric Actuator’s Micro-Displacement Amplifying Mechanism

Actuators
A non-contact piezoelectric actuator is proposed. The non-contact power transfer between stator and rotor is realized by pneumatic transmission, characterized by fast response, long life, compact structure, and easy miniaturization and control.

Exploiting Device Deformability for Fluid and Particle Manipulation

Small, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Dynamics of a Shell-Type Amplified Piezoelectric Actuator

, 2018
A dynamic model for a shell-type amplified piezoelectric actuator (APA) is proposed. The dimensions of the shell of a typical shell-type actuator allow one to model it as a set of connected beams.

Binary‐Solvent‐Programmed Single‐Step Inkjet Printing of Self‐Confined Micro‐Inlaid OLED Arrays

Small Methods, EarlyView.
Solvent‐programmed micro‐inlay inkjet printing enables lithography‐free, high‐resolution μ‐OLED arrays in a single step. A thermodynamically tuned 3:1 (w/w) chloroform/dichloroethane blend not only drives interfacial phase separation between the solute and polymers but also stabilizes droplet ejection, forming rim‐confined emissive domains in one pass.

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...
