Artificial muscles underlie exciting, novel technologies that have many wide-reaching applications: exoskeleton actuation, walker robots, prosthetics and stealthy underwater propulsion. Actuating these via electrostatic forces promises excellent energy efficiency output force density a high strength-to-weight ratio. Building through 3D-printed conductive microfluidics fast mass production at low cost. A microfluidic double-helix weave as potential solution for the architectural design of actuators has previously been reported. However, more recent experimental work showed architecture was not manufacturable necessary scale, given limitations current 3D-printing technology. Herein, several alternative architectures are presented. They advanced compatible with manufacturing requirements, offer additional benefits. The presented results confirm their improvements in manufacturability. These represent significant step towards proof principle practical implementation artificial muscles.

This study introduces a novel multi-degree-of-freedom (MDOF) piezoelectric motor (PEM) for high precision and 10 × mm2 large travel range within rigid compact structure (33 33 30 mm3). The consists of four tubes (PTs) arranged mounted parallel to each other enable controlled movement along both the X Y axes by using sawtooth waveform with time-delay control strategy. design features moving plate clamped between two upper lower sapphire balls, balls supported CuBe springs, ensuring symmetric precise movement. Applying individual driving signals PT induces bending deformation sequentially in same direction, followed simultaneous recovery original position, thereby enabling plate. Experimental results demonstrated that operated effectively at signal frequency 150 Hz, minimum voltage 18 V required detectable motion. exhibited capability produce step sizes from 0.53 6.23 µm linear relationship (±30 ±180 V) size, consistent performance. hysteresis analysis revealed minimal energy loss, ratios 5.2% on axis 4.16% axis, indicating motor’s efficiency. Additionally, sustained load 120 g while traversing area, continuous operation 12 h no significant performance degradation. reliable this MDOF PEM holds potential applications confined spaces, such as small-bore superconducting magnets, large-area atomic resolution imaging magnetic property measurements.
