Abstract: A dielectric elastomer including a crosslinked network comprising a polypropylene oxide) unit on a network chain or a pendant group. In another example, the dielectric elastomer is stacked in a multi-layer dielectric elastomer structure comprising two adjacent dielectric elastomer layers, a layer of a. conductive network sandwiched between the two adjacent dielectric elastomer layers, and. a polymer layer binding the conductive network and the two adjacent dielectric elastomer layers. The dielectric elastomer can be used as an actuator or artificial muscle in a variety of robotic, haptic, or wearable devices. In one or more examples, the dielectric elastomer has a strain, including an area strain, greater than least 100% in response to the electric field less than 150 Volts per micron and converts at least 10% of inputted electrical energy to mechanical work.

Abstract: A membrane for water collection may include a sheet having a top surface and a bottom surface, and a plurality of conical structures disposed on the top surface of the sheet, the conical structures comprising a hydrogel material. Each conical structure of the plurality of conical structures may have a height of 1 mm to 50 mm, wherein height is measured from the top surface of the sheet to an apex of a conical structure. Each conical structure of the plurality of conical structures may have an apex angle of 10 to 60 degrees.

Abstract: The present application discloses a prison monitoring intelligent control method with comparative analysis function, establish a identifier-age-type model based on the correspondence between each imprisonment identifier and the age and crime type of the corresponding imprisoned person, and store the identifier-age-type model, determine the abnormal level of the two imprisoned persons based on the total duration of the meeting, querying the age and/or crime type corresponding to the two imprisoned persons in the identifier-age-type model, according to the abnormality level; formulating an early warning strategy based on the analysis results of the age and/or crime type of the two imprisoned persons and feedback.

Abstract: The present application discloses an intelligent monitoring control system based on the analysis of prisoner information. Model building module is configured to establish a identifier-time-age model and store. Information counting module is configured to count the sleep time, the sleep duration, the average sleep time, and the average duration of each prisoner in the prison form days. Information regularization module is configured to determine the abnormality level of the prisoner. Intelligent control module is configured to formulate an early warning strategy based on an analysis result of the imprisonment time and/or age of the prisoner and feed back. The present application compares the sleep situation of each prisoner in the prison with his historical sleep condition to judge whether the prisoner has potential danger.

Abstract: Disclosed herein are self-healing conductive network compositions. The networks can contain one or more conductive polymers and one or more supramolecular complexes. The supramolecular complex can be introduced into conductive polymer matrix, resulting in a network of the two components. In this network, the nanostructured conductive polymer gel constructs a 3D network to promote the transport of electrons and mechanically reinforce the network while the supramolecular complex contributes to self-healing property and also conductivity. The networks disclosed herein are useful for various applications such as self-healing electronics, artificial skins, soft robotics and biomimetic prostheses.

Abstract: Disclosed herein are novel conductive films exhibiting graduated electrical resistance. The films can be prepared by asymmetrically oxidizing conductive film, thereby increasing electrical resistance along a gradient. The films can advantageously be employed in salt-water energy harvesters.
