Abstract: An acoustic tweezer is disclosed. The acoustic tweezer includes a function signal generator configured to generate a function signal for an ultrasound signal, a power amplifier configured to amplify the ultrasound signal based on the function signal, and an ultrasound transducer of a single channel in which a hologram thin film having different thin film thicknesses for each region is attached to an ultrasound oscillating surface of the ultrasound transducer, and the ultrasound transducer is configured to generate a plurality of ultrasound signals having different phase differences by allowing an oscillated ultrasound signal to pass through the hologram thin film.

Abstract: A stimulation apparatus using low intensity focused ultrasound, which has a low intensity ultrasound focusing array having a plurality of transducers for outputting low intensity ultrasound beams, and a fixing device to which the low intensity ultrasound focusing array is attached, the fixing device being configured to fix the low intensity ultrasound focusing array to an upper body of a user. The low intensity ultrasound beams outputted from the transducers are focused to at least one focus. The focus is positioned to a spinal cord of the user or nerves around the spinal cord so that low intensity ultrasound stimulation is applied to the spinal cord or nerve cells of the nerves around the spinal cord.

Abstract: The training apparatus according to an embodiment includes: a support unit; a guide unit fixed on the support unit and including rails which extend in a front-rear direction; a sliding unit which is movable in the front-rear direction along the rails of the guide unit; a pillar-shaped rotation axis fixed on the support unit; a footrest unit which supports a user's foot; a lower support formed below the footrest unit; and a connection rotating unit formed below the footrest unit and connected to the rotation axis of the support unit through insertion to allow the footrest unit to rotate around the rotation axis. A plurality of springs installed inward from two sidewalls of the sliding unit is configured to come into contact with the lower support of the footrest unit and apply pressure from two sides when the footrest unit rotates.
