Abstract: A helmet-type low-intensity focused ultrasound stimulation device includes: a first guide part formed in an arc shape and provided in a longitudinal direction; a second guide part which is formed in an arc shape and is connected in a transverse direction so as to be orthogonal to the first guide part; an ultrasound module which is connected to the second guide part and includes a transducer for generating ultrasound waves moving towards an inner direction; and a support part which is worn on a head of a user, and to which the first guide part is fixed and both end portions of the second guide part are rotationally fixed, in which the second guide part rotates in the longitudinal direction by allowing one point thereof to be guided along the first guide part, and the transducer is movable along the second guide part in a transverse direction.

Abstract: Disclosed is a device for measuring impedance within a human body, including: a spiral base plate; a plurality of electrodes arranged along the spiral base plate; and a plurality of first and second power lines connected to the plurality of electrodes. According to the present invention, the spiral base plate is used, so that it is possible to easily apply the device in accordance with a curve of a human body.
