The present disclosure is drawn to skin care devices. An example skin care device can include skin-rejuvenation head with a first external region including an array of skin-cleansing bristles and a second external region including an auxiliary skin-treatment appliance of a different type than the skin-cleansing bristles. The skin-rejuvenation head can include a vibrational motor positioned therein to provide vibratory oscillation to both the skin-cleansing bristles and the auxiliary skin-treatment appliance. A support rod can be mechanically coupled to the skin-rejuvenation head. A handle can include a neck portion and a grip portion, with the support rod also coupled to the handle. The neck portion can be proximal to the skin-rejuvenation head and the grip portion can be distal to the skin-rejuvenation head. The neck portion can include an energy dampening sleeve around the support rod, leaving a gap around the support rod.

Electrical current can be delivered to the skin to treat hyperhidrosis or other conditions using wearable and non-wearable devices. Wearable devices to deliver electrical current can include an inner assembly that carries one or more electrodes and an outer assembly that can be worn over the inner assembly. Contact between electrodes and the user's skin can be promoted using suction, support components, or filler materials. Non-wearable devices can be grasped by a user or otherwise placed into contact with a treatment site for delivery of electrical current to the user's skin. Electrode lay-out for wearable and non-wearable devices can be optimized for current density distribution across the electrode.

An electric current stimulation device includes a first electrode and a second electrode that are arranged in a body, and an output circuit that outputs an electric signal; wherein the electric signal by which the user feels no pain is output from the output circuit, and the electric signal is applied to a distal portion of extremities or near the same by the first electrode and the second electrode when arranging the body at the distal portion of the extremities of the user or near the same.

A posture correcting device using vibration or emitted electrical pulses in a pre-determined time sequence that may be adjusted in timing, intensity or strength, and a device for securing said posture correcting device to a body of a wearer.

Methods are provided for treating diseases by altering body mass composition in a human subject through application of galvanic vestibular stimulation (GVS) using electrodes placed in electrical contact with the subject's scalp at a location corresponding to each of the subject's left and right vestibular systems. The methods may be used to treat obesity-related diseases such as diabetes, hypertension, type 2 diabetes mellitus and osteoporosis. GVS may be applied for a predetermined period of time at regular intervals.

Systems, devices, and methods for use in delivering stimulation to the head of a patient, including examples directed to delivering electrical or other stimulation to the eye of the patient. In some examples eyepieces or eyepatches are configured to deliver electrical or other stimulus to the eye of a patient by being worn on the face of the patient.

Provided is an electrical stimulus device including a member to be wound around an arm of a user, multiple electrodes arranged on one surface of the member, and multiple optical distance sensors arranged on the one surface of the member. An electrical stimulus signal output from an electrical stimulus generation circuit is provided to the user from a specific electrode of the multiple electrodes to provide a stimulus to a muscle of the arm at a position facing the specific electrode, and the multiple optical distance sensors detect displacement of muscles of the arm. Some electrodes of the multiple electrodes are substantially rectangular electrodes inclined with respect to a circumferential direction of the arm of the user at a predetermined angle of lower than 90.

The present invention relates to a three-dimensional negative pressure stimulator module capable of performing customized composite stimulation for the improvement of skin functions that applies three-dimensional negative pressure stimulation as well as composite stimulation such as electric current stimulation, light stimulation, and thermal stimulation, which is helpful in improving functions of the skin, to skin compositively, and further has a function of sensing a skin state, thereby performing customized composite stimulation. The three-dimensional composite stimulator module includes: a negative pressure cup; and at least one diaphragm provided along the transmission path of the negative pressure of the negative pressure cup, wherein at least any one of negative pressure stimulation, light stimulation, thermal stimulation, and electrical stimulation is transmitted compositively to the skin or subcutaneous tissues.

This application discloses an improved approach for delivering alternating electric fields (e.g., TTFields) at a therapeutically effective strength to a target region of the spinal anatomy. In some embodiments, first and second sets of electrode elements are positioned with their centroids adjacent to upper and lower portions of the person's spine, respectively. In other embodiments, a first set of electrode elements is positioned with its centroid on an upper surface of the person's head, and a second set of electrode elements is positioned with its centroid adjacent to the person's spine (e.g., below the L3 vertebrae). Applying an AC voltage between the first and second sets of electrode elements generates a generally vertical field in the target region at levels that are not achievable using other layouts for positioning the electrode elements on the subject's body. These configurations are particularly useful for preventing and/or treating metastases.

This application discloses configurations for arranging transducer arrays on a person's head to impose tumor treating fields (TTFields) in the brain at field strengths that are as uniform as possible throughout the entire brain. In some embodiments, L-shaped sets of electrodes are positioned near the right and left ears, each with a horizontal arm above the ear and a vertical arm behind the ear. Optionally, these embodiments may be combined with a second pair of electrodes positioned on top of the head and behind the neck. In other embodiments, one pair of electrodes is positioned above the right ear and on the left/rear portion of the neck; and a second pair of electrodes is positioned above the left ear and on the right/rear portion of the neck. These configurations improve the uniformity of the electric fields imposed throughout the brain, and are particularly useful for preventing and/or treating metastases.
