A display device includes a display panel comprising a through hole and a pixel area, the pixel area surrounding the through hole and including pixels for displaying an image; a force sensor at a first surface of the display panel and configured to sense force applied from an outside; and a light sensor overlapping the through hole of the display panel in a thickness direction of the display panel, the light sensor being configured to sense light incident on the light sensor through the through hole.

Systems, methods, and devices relating to a sensor array for use with a user's finger segment and which indirectly maps the topography of a surface under the finger segment. Each sensor array is worn on a user's finger segment and has multiple sensitive strain gauges as well a positioning sensor. The multiple strain gauges are deployed around the periphery or sides of the finger segment. Each strain gauge measures the deformation of the finger segment pad as the finger segment passes over the surface topography. The relative ratios of the deformation detected indicates the location of a feature or contact point on the topography relative to the group of strain gauges. The positioning sensor determines the array's orientation as well as its location relative to a predetermined global reference frame.

A device for detection of the tactile sensitivity of a user includes a base frame and a mechanical system joined to the base frame, the mechanical system being movable relative to the base frame and having a resting area for the fingertip of at least one finger of the user. The mechanical system includes a plurality of movable plate-shaped members arranged side by side to each other so that the resting area is defined by the thicknesses of at least part of the upper edges of the plate-shaped members. Each plate-shaped member is connected to an actuator, which can be operated to independently move each plate-shaped member from a minimum height position to a maximum height position, a control unit being further provided, which is adapted to operate the actuators.

A surgical device for providing haptic feedback includes a housing having a cavity defined therein configured to receive a finger of a user and an elongated shaft configured to extend through the housing and into the cavity and configured to support a spring thereon and a pressure contact. A fluid-filled sensor is included that has a plurality of tubes configured to extend from the cavity, each tube includes a fluid-filled bladder at both ends thereof joined by a fluid channel therebetween. Each tube is configured to contain a fluid therein such that when a user's finger is engaged between the fluid-filled bladder at the proximal end of the tubes and the pressure contact, changes in pressure in the fluid-filled bladders at a distal end of the tubes is correspondingly registered in the fluid-filled bladders at the proximal end of the tubes providing haptic feedback to the user.

A chest tube insertion test device for performing a chest tube insertion training procedure at least partially encloses an insertion tool and includes a microcontroller communicatively coupled to one or more force-sensing resistors. The one or more force-sensing resistors convert an insertion force into a voltage signal sent to the microcontroller. A feedback generator compares the chest tube insertion force to one or more predetermined threshold values and provides feedback to a trainee. The feedback can include an instruction to increase, decrease, or maintain the chest tube insertion force. The feedback is one or more audio cues and/or one or more visual cues (e.g., represented by audio files and/or visual data files stored at the chest tube insertion test device). The chest tube insertion test device detects an insertion force rate of change indicating that the insertion tool has passed through an inner pad of the training model.

The present invention is directed to a method for health monitoring using one or more sensors comprising first measuring (100) a body composition via one or more sensors. The measured body composition is then classified (102) into one of a plurality of categories. An at least one setting to be used for the health monitoring is adjusted (104) based on the classified body composition. Then, the health monitoring is performed (106) using the adjusted at least one health monitoring setting, wherein at least one of the sensors used to measure the body composition may also be used to perform the health monitoring.

A stretchable sensor is provided. The stretchable sensor includes a first stretchable electrode including a first elastomer and a first conductor dispersed in the first elastomer, a stretchable active layer formed on the first stretchable electrode and including a third elastomer and an ion conductor dispersed in the third elastomer, and a second stretchable electrode formed on the stretchable active layer and including a second elastomer and a second conductor dispersed in the second elastomer. The stretchable sensor is effectively capable of sensing a temperature without being affected by strain and recognizing strain without being affected by temperature.

A mobile-platform imaging device uses compression of the target region to generate an image of an object. A tactile sensor has an optical waveguide with a flexible, transparent first layer. Light is directed into the waveguide. Light is scattered out of the first layer when the first layer is deformed. The first layer is deformed by the tactile sensor being pressed against the object. A force sensor detects a force pressing the tactile sensor against the object and outputs corresponding force information. A first communication unit receives the force information from the force sensor. A receptacle holds a mobile device with a second communication unit and an imager that can generate image information using light scattered out of the first layer. The first communication unit communicates with the second communication unit and the mobile device communicates with an external network.

An apparatus for estimating bio-information based on pulse wave signals of multiple wavelengths is disclosed. The bio-information estimating apparatus may include: a sensor part comprising a pulse wave sensor configured to measure a multi-wavelength pulse wave signal at a first point in time when a first pressure is applied from an object to the sensor part and at a second point in time when a second pressure is applied from the object to the sensor part; and a processor configured to estimate bio-information based on a difference between the multi-wavelength pulse wave signal measured at the first pressure and the multi-wavelength pulse wave signal measured at the second pressure.

An apparatus for estimating bio-information includes a pulse wave sensor configured to measure a pulse wave signal from an object, for a predetermined period of time, a processor configured to extract DC components of the pulse wave signal measured for the predetermined period of time, normalize the extracted DC components, based on at least one of the extracted DC components of the pulse wave signal measured at a time when a reference force is applied by the object to the pulse wave sensor, and estimate the bio-information, based on the normalized DC components.
