Active Cells for Multifunctional Structures
Abstract
This research effort explored the development of active engineered cells that exist as a self-contained electromechanical unit, with sensor/actuator, drive electronics, and battery embedded within a spherical elastomer housing. These building blocks will ultimately enable the creation of articulated structures in a straight-forward molding process: a large number of inexpensive, independently functioning sub-centimeter actuator units ('cells') are cast en masse as aggregate and joined via a flexible support matrix. Within a larger structure, each cell is autonomous and receives power and control signals wirelessly from distributed transmitters. Selective activation of clusters of cells through these transmitters produces the desired deformation of the structure. The absence of hardwired connections to each actuator unit streamlines fabrication significantly by allowing cells to be embedded as aggregate in resin or elastomer composites.
