Abstract:
A soft robotic device with one or more sensors is described. The sensor may be embedded in the soft body of the soft robotic device, attached to the soft body of the soft robotic device, or otherwise linked to the soft body of the soft robotic device.
Abstract:
In an aspect, a device includes a substrate including a cellulose matrix that provides an interconnected porous structure, a hydrophobic barrier disposed through the thickness of the substrate to define at least one porous channel within the volume of the cellulose matrix, and an electrically conducting material. The electrically conducting material is disposed within the volume of the porous channel to coat at least a portion of the cellulose matrix therein. A method of making and using actuators, electrochemical sensors, and batteries based on the device are also disclosed.
Abstract:
A fluid gating valve includes a porous hydrophobic layer which acts a barrier for liquid flow; a liquid source on one side of the porous layer; a liquid drain on the opposing side of the porous hydrophobic layer; a source electrode in electrical connection with the liquid source; and a gate electrode electrically insulated from the liquid source, wherein the source electrode and the gate electrode are positioned and arranged to be connectable to a voltage source. And valve can be open by applying voltage between the gate and the source electrodes.
Abstract:
A method of and system for detecting a gas or vapor includes providing a sensor comprising an electrode pair in electrical contact with a layer of porous material, the porous material layer having water adsorbed on its surface; contacting the sensor with a gas or vapor sample to be analysed; applying a voltage across the electrode pair of the sensor; and measuring a response, the response correlating to the presence of a target gas or vapor.
