A rotary engine that generates electricity using differences in relative humidity. A water-responsive material expands and contracts as water evaporates which drives the rotation of two wheels. The rotary motion drives an electrical generator which produces electricity. In another embodiment, the water-responsive material is used to actuate an artificial muscle of a robotic device.

Water-responsive materials and uses therefor

A thin film that has a flexible polymer layer and a peptide layer. The peptide layer is disposed on the flexible polymer layer and has a peptide selected from HYF, DYF and YFD. The thin film reversibly curves with changes in humidity.

Humidity-responsive tripeptide crystal

The present disclosure relates generally to facilitating routing of communications. More specifically, techniques are provided to dynamically routing messages having multiple intents between bots and terminal devices during communication sessions configured with multi-channel capabilities.

Bot supervision

Water-responsive actuators and methods for creating water responsive actuators are disclosed. In some embodiments, the disclosed subject matter includes a first layer, for example a plastic tape, and a second layer, for example bacterial spores and cured adhesive. The second layer can be created in a pattern. The pattern can include joints, which can contract when exposed to dry air and can thereby bend the actuator, and can expand when exposed to humid air and thereby return the actuator its original position.

Systems and methods for fabricating water-responsive actuators

Evaporation-driven engines are disclosed herein. An example engine can include a water source having a high humidity zone proximate the surface of the water source, a supporting structure, and a hygroscopic material disposed on the supporting structure and configured to generate mechanical force in response to a changing relative humidity. The hygroscopic material can be repeatedly exposed to the high humidity zone and removed from the high humidity zone thereby causing the hygroscopic material to generate mechanical force.
