  • Patent number: 11569760
    Abstract: A triboelectric energy generator (1) comprises a first generating element (8) and a second generating element (10). The first generating element comprises a first triboelectric material (9) and the second generating element comprises a second triboelectric material (13). Movement of the second generation element relative to the first generation element results in an output voltage, as a consequence of the triboelectric effect. A stopper (7) is configured to restrict rotation of the second generating element, so that the second generating element may only rotate through a desired angle.

  • Patent number: 11564582
    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.

  • Patent number: 11563163
    Abstract: A field-driven electroactive polymer actuator is provided with a current sensor for sensing a current flowing to the actuator. A control circuit is used for driving the actuator which includes a voltage source. The driving of the actuator is controlled in dependence on the sensed current, thereby to provide a predetermined charge delivery for particular changes in actuation level of the actuator. This provides a combined voltage-based and current-based drive scheme for a voltage-driven EAP actuator, and it enables mechanical movements of the actuator to be more reliably repeated.

  • Publication number: 20220313123
    Abstract: Provided is a system for correcting a sweat analyte measurement for temperature. The system comprises a sweat collector (106) for collecting sweat from skin (102). The collected sweat is drawn from the sweat collector to an outlet (110) via a capillary (108). The sweat is drawn through the capillary by capillary action and evaporation of the sweat from the outlet. The evaporation of the sweat from the outlet depends on the temperature. A flow sensor (112) measures a flow rate of the sweat being drawn through the capillary. An analyte sensor (114) obtains the sweat analyte measurement. The system further comprises a controller which is configured to determine a temperature from the measured flow rate. The sweat analyte measurement is then corrected using the determined temperature.

  • Patent number: 11362258
    Abstract: An electroactive polymer actuator includes an electroactive polymer structure and a driver for providing an actuation drive signal. In one aspect, a first drive level is used to charge the electroactive polymer structure from a non-actuated state to an actuated state. When or after the electroactive polymer structure reaches the actuated state, a lower second drive level is used to hold the electroactive polymer structure at the actuated state. This temporary overdrive scheme improves the speed response without damaging the electroactive polymer structure. In another aspect, a driving method makes use of several different level segments over time, which compensates for the delayed actuation response of the EAP actuator.
