The present disclosure provides apparatuses and methods for measuring capacitance as an indication of susceptibility to the formation of a diabetic foot ulcer.

An automatic tattoo apparatus can be used to robotically apply tattoos. A customer can shop on an online tattoo marketplace to select designs created by various artists located anywhere. The online tattoo marketplace can process and manage payments, artist and/or customer profiles, bookings, tattoo design uploads, browsing and design selection, design changes, and/or perform other actions. The automatic tattoo device can apply tattoos precisely, quickly, and may with reduced pain. The tattoo apparatus can apply a wide range of different types of tattoos, including but not limited to micro tattoos, dotwork, blackwork tattoos, realism tattoos, fine-line tattoos, etc.

An evaluation system including a hardware system for collecting real-time data for evaluating sleeping comfort performance of a bedding system is disclosed. The hardware system includes a thermal and moisture comfort measurement system, a thermal and moisture comfort control system, a biomechanical comfort control system, and a biomechanical comfort measurement system. The evaluation system also includes a computational system having a processor and a tactile database, and a portable device. The computational system is configured to receive and process the real-time data from the hardware system, and is communicatively connected to the portable device for transmitting real-time data for evaluating the bedding system and adjusting the hardware system. A mobile application executable on the portable device is configured to collect subjective opinion of the sleeper using questionnaires, and the processor is configured to perform combined analysis of the subjective opinion and the real-time data of the bedding system.

Systems, methods and apparatuses for performing wound analysis using THz imaging are provided. Due to the large complex component of water's dielectric constant in the THz regime, and the relative frequency invariance of non-aqueous tissue constituents, this modality is highly sensitive to the water content of tissue. It has been found that using THz imaging turns the presence of edema into a contrast mechanism, and allows for the use of the spatial distributions of edema to assess wound status immediately. Apparatus and methods enable earlier diagnosis of wound status which could result in accelerated treatment and shorter overall hospital stays.

In one embodiment, a personal care implement is disclosed. The personal care implement has an emitting end and an electromagnetic source for projecting electromagnetic radiation onto an area of skin to treat a skin condition. A light sensor is configured to sense an amount of ambient light present at the emitting end. A controller instructs the electromagnetic source to begin projecting only when the light sensor senses that the amount of ambient light at the emitting end is below a predefined threshold.

Techniques for automatic measurement using structured lights are provided. A computer system uses structured lights to acquire skin information, the skin information being associated with at least one affected area of the skin. The computer system determines parameters related to the at least one affected area of the skin, at least partly, on the skin information and generates an assessment for the at least one affected area of the skin.

An optical system for the detection of skin disease, such as melanoma, acquires images of a lesion on a subject's skin at different wavelengths and utilizes a sweeping arm rotating about the lesion in a clock-like sweep to produce diagnostically relevant metrics and classifiers from the image data so as to enhance detection of the skin disease.

Disclosed is a portable hyperspectral/multiple spectral imaging device. The imaging device has a chassis having a base face and an axis orthogonal to the base face. The chassis includes an inner perimeter wall extended substantially around the axis and enclosing an interior region of the chassis. The chassis also includes one or more outer walls extended at acute angles with respect to the base face and arranged around the inner perimeter wall. One or more light sources are disposed on the outer walls. The imaging device further comprises a lens, an optical filter, and an optical detector disposed within the interior region. The imaging device further comprises a control system and a low-voltage power source.

An electrode can comprise carbon black and one of polydimethylsiloxane (PDMS) or PVA, wherein the carbon black has a weight of between 10% and 50% of a weight of the PDMS or PVA. The electrode can be suitable for bioelectronics. A pattern of hydrogel can be deposited on the electrode for providing adhesion to a subject. The electrode can be used in wound treatment and/or monitoring devices or in various other bioelectronics applications.

Methods for treating tissue are provided. In one embodiment, an adjunct material, when secured to tissue, can receive at least one physiological element released from the tissue during healing progression of the tissue, and can exhibit first and second stiffnesses in compression that are approximately constant during first and second time periods from contact with the tissue, with the second stiffness decreasing with time as a function of at least one of oxidation, enzyme-catalyzed hydrolysis, and change of pH resulting from interaction with the at least one physiological element. In another embodiment, the adjunct can receive a unit volume of fluid that causes first and second portions of the adjunct to expand according to first and second expansion behaviors that differ from one another to apply different pressures to the tissue.
