Here, we present a protocol to fabricate a unique two-layer microfluidic device to study the electromechanical regulation of epithelial tissue homeostasis. The device applies static physiological electric currents perpendicular to the tissue plane, impacting cell-cell adhesion, proliferation, and extrusion. Live-cell imaging and mechanical stress measurements reveal mechanisms of these processes.

Isolating electrical and thermal effects on electrically assisted deformation (EAD) is very difficult using macroscopic samples. Metallic sample micro- and nanostructures together with a custom test procedure have been developed to evaluate the impact of applied current on the formation without joule heating and evolution of dislocations on these samples.

Physical and Chemical Properties of Matter

The characteristics that enable us to distinguish one substance from another are called properties. Physical Properties of Matter A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter...
FAQs
Piezoelectric coupling can operate in two directions: an applied electric field produces strain, and mechanical stress generates an electrical potential. Electrostriction also produces deformation under an electric field, but it represents a separate field-induced mechanism rather than the stress-to-potential response described for piezoelectric materials. Distinguishing these pathways helps researchers interpret electromechanical behavior.
Chemical composition can influence crystal structure, molecular organization, and interfaces, all of which shape how electrical and mechanical behavior are connected. Examining these relationships allows chemists to move beyond observing a response and instead identify material features associated with charge transport and mechanical performance. That knowledge supports deliberate tailoring of electromechanical materials.
The relevant performance priorities are not identical for every use. Sensitivity matters when a device must respond to a stimulus, durability matters when performance must be maintained, and efficiency matters when energy conversion or operation is important. Chemists therefore connect composition and structure with both electrical response and mechanical performance when refining a material.
An investigation can be organized around the relationships among composition, crystal structure, molecular organization, interfaces, charge transport, and mechanical performance. Researchers relate these chemical and structural features to the material’s electrical behavior and mechanical response, then use the observed connections to guide material design. This framework applies to ceramics, polymers, and other responsive materials.
Piezoelectric ceramics and polymers are important material classes for studying these effects, while their inclusion also highlights the value of chemical and structural control. Electromechanical properties can then be considered in designs for sensors, actuators, energy-harvesting devices, flexible electronics, and responsive materials. The intended application determines which balance of performance characteristics is most useful.
Interfaces are included in the chemical analysis because they connect material regions and can affect the relationship between electrical behavior and mechanical performance. Considering them alongside composition, crystal structure, and molecular organization gives a more complete basis for understanding a material’s response. This perspective is especially relevant when designing flexible and other responsive materials.
