A method and device is taught to improve the appearance of cellulite by combining mild exfoliation of the skin, various wavelengths of low level light, ultrasound, and a vacuum or suction. The device is intended to increase the metabolic rate of the fat cells and reduce their size, while increasing the extensibility or length of the septae. Such increased activity will promote blood flow to the affected area thereby increasing cell nutrients and removing cellular exudates while stimulating the growth of new collagen thereby alleviating the cellulite.

A contact lens configured to decrease dark adaptation comprises one or more LEDs and directs light from the LED away from the fovea and toward the parafovea or perifoveal regions of the retain. In some embodiments, soft contact lens embedded with one or more arrays of microLEDs and electronics operating the LEDs is configured to be worn at night in order to inhibit dark adaptation and reduce oxygen consumption by the rods. The contact lens may be made of a single layer of a contact lens material or multiple layers sandwiching a flexible transparent plastic layer comprising the electronics and the LED arrays. The contact lens may be made of a hydrophilic hydrogel material that is biocompatible to the human cornea, or a silicone hydrogel material. The contact lens may be spherical and may provide refractive correction to the eye of the wearer.

A system and method for modulating optogenetic vagus neurons in a noninvasive and transcutaneous manner is disclosed. The system and method comprises a two-dimensional array of organic light emitting diodes (OLEDs), a voltage-generating unit, a control unit, and a feedback loop. The array is placed on a subject's outer ear. Because the array is flexible, it can be closely placed on the skin of the outer ear. The array can deliver optical therapy and monitor heart rate variability (HRV) of the subject simultaneously, and the pixels of the array can be individually addressed. The voltage-generating unit generates pulsed voltage to the OLEDs. The control unit is connected to the array and controls the array and therapeutic patterns. The feedback loop uses the HRV to identify the therapeutic patterns.

A flexible device having a layered structure for delivering electrical stimulation and one or both of light and ultrasound to a skin surface is provided. The device is flexible so as to form a non-planar contact surface against the skin surface, and includes one or both of (a) a flexible light emitter layer positioned between two flexible conductive layers that emits light when driven by a power source and (b) a flexible ultrasound emitter layer positioned between two flexible conductive layers that produces ultrasound when driven by a power source. The device also includes a flexible electrical stimulation layer that functions as an electrode and is configured to provide electrical stimulation when driven by a power source.

A circadian entrainment enhancement device includes a housing, a first directional light source, a second directional light source, and a driver. During daytime, the driver turns on the first directional light source with a high melanopic ratio to enhance the daytime circadian entrainment of a user. During nighttime, the driver turns on the second directional light source with a low melanopic ratio to enhance the nighttime circadian entrainment of a user. A more advanced version of the present disclosure uses a light sensor, a memory module, and a computation module to calculate the necessary light output of the device by factoring the ambient light level into consideration. An even more advanced version of the present disclosure uses a distance sensor to adjust the light level of the light sources according to the distance between the device and the user.

A utility garment comprises a first layer and a second layer of a fabric, an infrared heater including a plurality of flexible heating elements, provided between the first layer and the second layer of the fabric, a plurality of Light Emitting Diodes (LEDs) provided between the first and the second layer of the fabric and a plurality of sensors configured to determine a plurality of parameters pertaining to a body by which the utility garment has been worn

The photo therapy apparatus of the present invention comprises one or more light sources which are integrated with a molar bite block for providing photobiomodulation therapy to the oral mucosa of a cancer patient suffering from (or at risk of) Oral Mucositis. The light sources can be either internal, or external to the bite block, and either lasers, light emitting diodes (LEDs), lamps, or any other types of light sources which produce therapeutic light in a desired wavelength range. The therapeutic light is delivered through the bite block to the oral mucosa. The delivered light produces a photochemical and photophysical process e.g. increase the blood flow and circulation. This photochemical and photophysical process helps to reduce the incidence and severity of oral mucositis in cancer patients and helps improve outcomes of cancer therapy.

The present invention concerns a solid nanocomposite material consisting of a polymer-matrix in which are dispersed alkali metal, hydronium or ammonium salts of polyanionic components,

wherein the polymer-matrix comprises at least a linear or branched polymer or copolymer containing one or several poly(ethylene oxide) (PEO) chains, said polymer or copolymer being optionally crosslinked and each PEO chain having at least 4 ethylene oxide monomer units.

The present invention relates also to a photonic, e.g. optoelectronic, device comprising such a nanocomposite material.

Such material and device can be used as phosphorescence emitter, for crop growth lighting or for generating singlet oxygen.
