Microscale soft-robots hold great promise as safe handlers of delicate micro-objects but their wider adoption requires micro-actuators with greater efficiency and ease-of-fabrication. Here we present an elastomeric microtube-based pneumatic actuator that can be extended into a microrobotic tentacle. We establish a new, direct peeling-based technique for building long and thin, highly deformable...

background: elastomeric chains are commonly used in orthodontics. force decay in these materials poses clinical problems. the aim of this study was to evaluate the effects of three different mouthwashes on the force decay of orthodontic chains. materials and methods: in this experimental study, elastomeric chains with two different confi gurations were divided into eight groups (two control and...
