Title: Soft actuators and soft actuating devices

Abstract

A soft buckling linear actuator is described, including: a plurality of substantially parallel bucklable, elastic structural components each having its longest dimension along a first axis; and a plurality of secondary structural components each disposed between and bridging two adjacent bucklable, elastic structural components; wherein every two adjacent bucklable, elastic structural components and the secondary structural components in-between define a layer comprising a plurality of cells each capable of being connected with a fluid inflation or deflation source; the secondary structural components from two adjacent layers are not aligned along a second axis perpendicular to the first axis; and the secondary structural components are configured not to buckle, the bucklable, elastic structural components are configured to buckle along the second axis to generate a linear force, upon the inflation or deflation of the cells. Methods of actuation using the same are also described.

Electrically actuatable doped polymer flakes and electrically addressable optical devices using suspensions of doped polymer flakes in a fluid host

Patent Trajkovska-Petkoska, Anka; Jacobs, Stephen D.; Marshall, Kenneth L.; ...

Doped electrically actuatable (electrically addressable or switchable) polymer flakes have enhanced and controllable electric field induced motion by virtue of doping a polymer material that functions as the base flake matrix with either a distribution of insoluble dopant particles or a dopant material that is completely soluble in the base flake matrix. The base flake matrix may be a polymer liquid crystal material, and the dopants generally have higher dielectric permittivity and/or conductivity than the electrically actuatable polymer base flake matrix. The dopant distribution within the base flake matrix may be either homogeneous or non-homogeneous. In the latter case, themore » « less

Coupled memristor devices to enable feedback control and sensing of micro/nanoelectromechanical actuator and sensors

Patent Almeida Loya, Sergio Fabian; Zubia, David; Garcia, Ernest J.; ...

A MEMS apparatus with dynamic displacement control includes a MEMS parallel plate capacitor integrated with one or more memristors in a series configuration wherein a displacement is observable as a function of memristance, such that an upper electrode position is capable of being interpreted in a form of a resistance rather than a capacitance. The current is limited by said MEMS parallel plate capacitor restricting a change in the resistance of the memristor(s). The memristor(s) can be employed in some embodiments a sensor element to improve a MEMS operation range.
