Abstract:
The proposed device includes two segments adapted to enclose a body part in a form-fitting manner. Each segment contains an electroactive-material-based actuator, which is adapted to receive an electrical control signal and in response thereto adjust the actuator's morphology, so as to cause the segment to apply a basic pressure profile to the body part. A pressure transition is adapted to redistribute the basic pressure profiles between the first and second segments. A control signal in respect of the first segment causes the pressure transition system to apply a first adjusted pressure profile to at least part of the second portion of the body part, and vice versa, a control signal in respect of the second segment causes the pressure transition system to apply a second adjusted pressure profile to at least a part of the first portion of the body part.

Abstract:
A system for monitoring a body includes a surgical implant configured for implantation within a body, a sensory module coupled to the surgical implant and configured for implantation into the body in conjunction with the surgical implant, and a communication module coupled to the surgical implant and configured for implantation into a body in conjunction with the surgical implant. The sensory module is configured to monitor characteristics of the surgical implant, surrounding tissue and/or adjacent tissue. The communication module is electrically coupled to the sensory module and is configured to communicate a signal derived from said characteristics to an external entity.

Abstract:
An apparatus (10) for controlling flow of fluid from a wound site of a patient may include a chamber (28) connectable to a wound site and a reservoir (16). The chamber (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The chamber (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the chamber (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the chamber (28) from the second state to the first state.
Abstract:
A device for compressive treatment of a body part comprises a compression member, adapted to at least partly encircle the body part, and an actuation unit, arranged to tighten the compression member to provide a compressive force to the body part. The actuation unit comprises an active material actuator. There is also disclosed a system comprising such a device and methods for its therapeutic, cosmetic and non-therapeutic use and operation.
Abstract:
A transducer is designed and fabricated using stretched rolled electroactive polymers. The invention includes the design, fabrication, and integration of a stretched rolled actuator system with corresponding sensing, control and power subsystems. The invention presented is based on the improved performance of electroactive polymer transducers that can be achieve by prestretching the polymeric material. In this invention, the preferred stretch is maintained in a rolled configuration by introducing structural elements to the transducer. The structural elements facilitate fabrication of the transducer as well as provide a compact and efficient means of maintaining stretch and the desired boundary conditions on the electroactive polymer during operation. These conditions together are used to improve and tailor the strain response of the transducer.
