Abstract: A monitoring system includes an implantable intra-vascular support device for positioning against a vessel wall and an implantable sensor-actuator mounted to the support device. The sensor-actuator is drivable between a non-deployed position in which it is against the support device and a deployed position in which it is displaced away from the support device. Sensor signals are generated when in the deployed position. This system is able to monitor flow away from the edge of a vessel by deploying the sensor-actuator towards the center of the vessel. When flow monitoring does not need to take place, it can be non-deployed so that it does not present an occlusion to the flow.

Abstract: An actuator or sensor device comprises an electroactive polymer (EAP) arrangement which extends between fixed opposite ends. The electroactive polymer arrangement comprises a passive carrier layer and an active electroactive polymer layer, wherein at or adjacent the ends, the passive carrier layer and the active EAP layer are mounted with one over the other in a first order, and at a middle area between the ends, the carrier layer and the active EAP layer are mounted in an opposite order. This enables internal stresses and moments within the electroactive polymer arrangement to be used more effectively to contribute to displacement or actuation force.

Abstract: A device for treating skin includes a skin treatment member, a skin contacting surface, a mounting member for mounting the skin treatment member and the skin contacting surface, and a friction controlling device to control friction between the skin contacting surface and skin to be treated, in at least one controlled friction area of the skin contacting surface when the skin contacting surface is moved over the skin. The friction controlling device introduces a slip motion of the controlled friction area relative to the mounting member in a direction corresponding to a local direction of extension of the skin contacting surface. The device also includes a sensor for detecting a first parameter related to an amount of friction between the skin contacting surface and the skin during use, and the friction controlling device controls a second parameter of the slip motion in dependence on a value of the first parameter.

Abstract: The invention provides a health device for automatically administering skin pressure-based therapies to a user. The device comprises one or more actuator members, each comprising a smart shape-changing material of a class which is disposed to change shape in response to a change in temperature or to the application of an electrical stimulus. The actuator members are controlled by a controller to apply pressure to one or more points on a user's skin.

Abstract: An actuator device is provided having a controllable stiffness profile, wherein an actuator member (12) comprises an electroactive polymer material (16) having light absorbing filler elements (20) embedded therein. The filler elements are adapted to absorb and convert incident light (26) to heat energy to therefore heat surrounding sections of the electroactive material. By selectively controlling an intensity level or spectral composition of a light source (24) directed at the actuator member, a specific degree and spread of heating can be achieved across the member and, as a result, a specific desired stiffness or flexibility profile can be realised across the actuator member.

Abstract: An electroencephalography (EEG) system includes a support configured to be positioned at least partially around the head of a user, an EEG electrode configured to be supported by the support and to be positioned for contacting skin of the user, an actuator operatively coupled to the EEG electrode and configured to move the electrode in at least two dimensions, including an axial dimension and a lateral dimension to enable the EEG electrode to contact the skin at different locations, and one or more physical processors operatively connected with the EEG electrode and the actuator. The one or more physical processors being programmed with computer program instructions which, when executed cause the one or more physical processors to: obtain an impedance signal from the EEG electrode; and actuate the actuator to move the EEG electrode based on a comparison of the obtained impedance signal with an impedance threshold.

Abstract: An intravascular Doppler ultrasonic device comprises a tip region forming a fraction of a catheter body at a distal end thereof and carrying an ultrasound probe. The tip region is bendable in a direction perpendicular to a longitudinal direction. An actuator is provided in the tip region, which is configured to receive actuation drive power provided through the catheter body and to exert to the tip region a bending moment of a controllable amount. An actuation controller is configured to control actuation drive power delivery to the actuator so as to control the amount of the bending moment. A Doppler spectrum analysis unit is configured to receive Doppler spectrum data and to determine from it a Doppler signal quality measure indicative of a signal quality of the Doppler spectrum. The actuation controller is configured to determine the actuation drive power in dependence on the determined Doppler signal quality measure.

Abstract: An implantable blood flow control system has an open passageway defined inside a radially inner wall, behind which is a closed passageway. The radially inner wall includes electroactive polymer actuator members for providing a variable flow restriction. The flow restriction has an undulating shape so that the volume of the closed passageway may remain constant during actuation of the electroactive polymer actuator members. In this way, the chamber behind the actuator members does not impede free movement of the actuator members. The undulating pattern presents no sharp edges, where blood coagulation could otherwise occur.

Abstract: The invention provides an electroactive material (preferably electroactive polymer) sensor system, comprising an electroactive material sensor (22) and a control system (28) for performing measurements relating to the impedance of the electroactive material sensor at at least first and second different frequencies. From these measurements a temperature at the sensor and an external pressure or force applied to the sensor can be determined. The sensor can thus be used as a pressure sensor and as a temperature sensor. When used in combination with actuation, an electroactive material actuator with integrated temperature sensing functionality is able to measure the temperature at the exact actuator position, which is always closer than an external thermocouple.

Abstract: A monitoring system comprises an intra-vascular support device and a sensor mounted to the support device and projecting into the vessel. The sensor generates a signal which is dependent on the level of deformation of a free end. The sensor signal is interpreted to enable detection of changes in the length of a deformable part of the sensor thereby to determine a level of bio-layer formation and also determine a level of flow. The sensor remains able to detect flow even when a bio-layer is formed and it can also detect the presence (and thickness) of the bio-layer, because part of the sensor becomes rigid when constrained by the bio-layer.
