2016
Here, we fabricate 3D polymeric micro/nano structures in which both the shape and the molecular alignment can be engineered with nanometer scale accuracy by the use of direct laser writing. Light induced deformation of several types of liquid crystalline elastomer microstructures can be controlled in the microscopic scale.

In this two-part study, a biological actuator was developed using highly flexible polydimethylsiloxane (PDMS) cantilevers and living muscle cells (cardiomyocytes), and characterized. The biological actuator was incorporated with a base made of modified PDMS materials to build a self-stabilizing, swimming biorobot.

Polarization-based Total Internal Reflection Fluorescence Microscopy (pTIRFM) enables real-time detection of cell membrane dynamics. This article describes the implementation of pTIRFM for the study of membrane remodeling during regulated exocytosis. The technique is generalizable to other processes in cell biology that directly or indirectly involve changes in membrane shape.

Here we present techniques to measure red cell deformability and cellular heterogeneity by ektacytometry. These techniques are applicable to general investigations of red cell deformability and specific investigations of blood diseases characterized by the presence of both rigid and deformable red cells in circulation, such as sickle cell anemia.
FAQs
Directional control improves when actuator geometry and deformation directions are coordinated with the intended system motion. Alignment helps individual force or strain contributions reinforce the desired change in shape or position instead of producing competing movements. This coordination can make the overall mechanical response more predictable and improve actuation efficiency, repeatability, and structural stability.
Attachment points determine how locally generated forces or strains transfer into the surrounding structure. Their placement influences how separate actuator movements combine, whether the structure deforms in the intended direction, and how evenly the response is distributed. Evaluating attachment geometry is therefore essential for relating local actuator behavior to predictable system-level motion.
Environmental conditions can affect whether an aligned arrangement maintains its intended mechanical response and structural stability. A configuration that performs predictably in one setting may respond differently when conditions change or become demanding. Considering the operating environment during alignment helps researchers evaluate directional control, repeatability, and the reliability of the resulting deformation.
Researchers should examine actuator geometry, attachment points, deformation directions, intended motion, and the environmental conditions in which the system will operate. These factors must be considered together because changing one can alter how local movements combine into an overall response. The resulting assessment can identify arrangements that support efficiency, control, repeatability, and stability.
Carefully aligned actuators can support adaptive structures, soft robotic systems, deployable devices, and environmentally responsive materials. In each case, alignment connects material deformation with a larger functional response, such as a controlled shape or position change. This makes the approach relevant when systems must adapt mechanically while maintaining predictable behavior under changing or demanding environmental conditions.
Evaluation focuses on whether local actuator movements produce the intended overall change in shape, position, or mechanical response. Researchers can relate the observed system-level behavior to the chosen geometry, attachment points, deformation directions, and environmental conditions. Useful outcomes include evidence of improved actuation efficiency, directional control, repeatability, and structural stability.
