Udah pernah liat Magician bisa buat suatu objek melayang kan gan? Ane yakin hampir semua agan-aganwati disini udah pernah liat yang kayak begonoan..

Nah gan, Sekarang Udah ada yang neliti tentang tema yang kayak begitu. Peneliti dari jepang meneliti kalau sebenernya gelombang suara itu bisa dimanfaatin buat ngimbangin gravitasi dengan kata lain sebuah objek bisa dibuat melayang gan. Tapi dari yang ane liat videonya itu bendanya itu masih kecil ukurang 4 sentimeteran..

Keren gan..

Ini Nama papernya gan sama nama penelitinya

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. The acoustic axis of the ultrasound beam in conventional studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that expanded-polystyrene particles of 0.6 mm and 2 mm in diameter could be manipulated by our proposed method.

Cek For Videohh... Cuma 2 menitan gan buffer dikitlah.
