Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

Abstract: Disclosed are a cis-platinum cross-linked protein hydrogel and a preparation method thereof. Main components of the cis-platinum cross-linked protein hydrogel comprise the following ingredients in percentage by mass: 0.5% to 5.0% drug, 6.0% to 50.0% serum albumin and 47.0% to 93.0% solvent medium; a carboxyl group on a surface of the serum albumin and the drug form a coordinate bond; and the drug is cis-platinum. A hydrogel preparation is simple in structure and easy to prepare, and the used cis-platinum has dual effects: a cross-linking agent for promoting the formation of protein hydrogels and an antitumor drug for exerting a tumor inhibition curative effect. The strategy simplifies the carrier design and reduces potential toxic side effects. The protein carboxyl limits the release of cis-platinum through a coordination effect so that reduce the burst release of the loaded drugs drastically.

Abstract: A system may include one or more finger-mounted devices such as finger devices with U-shaped housings configured to be mounted on a user's fingers while gathering sensor input and supplying haptic output. The sensors may include strain gauge circuitry mounted on elongated arms of the housing. When the arms move due to finger forces, the strain gauge circuitry can measure the arm movement. The sensors may also include ultrasonic sensors. An ultrasonic sensor may have an ultrasonic signal emitter and a corresponding ultrasonic signal detector configured to detect the ultrasonic signals after passing through a user's finger. A two-dimensional ultrasonic sensor may capture ultrasonic images of a user's finger pad. Ultrasonic proximity sensors may be used to measure distances between finger devices and external surfaces. Optical sensors and other sensors may also be used in the finger devices.

Abstract: A system may include finger devices. A touch sensor may be mounted in a finger device housing to gather input from an external object as the object moves along an exterior surface of the housing. The touch sensor may include capacitive sensor electrodes. Sensors such as force sensors, ultrasonic sensors, inertial measurement units, optical sensors, and other components may be used in gathering finger input from a user. Finger input from a user may be used to manipulate virtual objects in a mixed reality or virtual reality environment while a haptic output device in a finger device provides associated haptic output. A user may interact with real-world objects while computer-generated content is overlaid over some or all of the objects. Object rotations and other movements may be converted into input for a mixed reality or virtual reality system using force measurements or other sensors measurements made with the finger devices.
