Electrodes providing excellent recording and physical stability. Electrodes are disclosed that may include a plurality of small teeth that possess a novel design shape and orientation. The shallow and relatively long teeth run parallel to the rim of the electrode that presses against the patient's skin. When the electrode is twisted onto skin, the tiny teeth penetrate the stratum corneum and move nearly horizontally under the stratum corneum, thus anchoring the electrode securely to the skin. The electrodes cause minimal discomfort to the patient since the small teeth do not extend to the pain fibers which are located in deeper layers of the skin. The electrodes may be fabricated in a variety of geometries including cylindrical, disk, and blunt bullet or top shapes. In some instances, the electrodes may be connected to detachable leads having magnetic properties.

Skin screw electrodes

An energy harvesting device includes a housing (), a moveable device () disposed within the housing and including a first surface including a first material () and a second surface including a second material (), wherein the moveable device is operable to move to bring the first and second surfaces together and apart to cause contact and separation between the first and second materials, a first strap () attached to the housing, a second strap () coupled to the moveable device, wherein movement of the second strap causes operation of the moveable device, and electronic circuitry () structured to harvest energy from the electrical charge generated by the contact between the first and second materials.

Electronic systems, devices and methods are provided to accurately record and analyze food intake and physical activity in a subject. A device is provided to be placed on a subject which records video using at least two video cameras positioned to record stereoscopic image pair, as well as other physiological and/or environmental data including, for example, oxygen saturation, heart rate, and environmental factors such as physical location, temperature, and humidity. Video data is analyzed along with other data obtained by the device to determine food consumption and/or physical activity of the subject, much of which is accomplished by automated computer-implemented processes.

Method, apparatus and system for food intake and physical activity assessment

Single-unit EEG sensors contain multiple closely spaced dry electrodes that can hook onto skin and associated electronic circuitry such as amplifiers, A/D convertors, wireless transmitters, and a power source such as a battery. The electrodes can be separated by about 20 mm or less, and the associated circuitry can be situated within a volume defined by the multiple electrodes. The single-unit sensors hook onto the skin using a tooth surface so that a rotation of the sensor secures and electrically connects the sensor to the skin.
