Cell stimulation and culture platform using ultrasonic hologram

A cell stimulation and culture platform using an ultrasonic hologram, comprising:

• a culture vessel in which a culture well with an open lower portion is formed;
• a transmission sheet which is installed to cover a lower surface of the culture vessel and where a biological sample is seated on a surface portion corresponding to the culture well;
• a platform body of which an inner space is filled with a liquid ultrasonic medium and an open upper end is covered by the transmission sheet;
• an ultrasonic transducer that is installed at an inner lower end portion of the platform body in a state of being spaced apart from the biological sample by a set distance to generate ultrasonic waves upward;
• and
• an ultrasonic hologram lens that is installed on the ultrasonic transducer, transmits the incident ultrasonic waves to a target surface on which the biological sample is located through the ultrasonic medium, and spatially modulates the phase of the ultrasonic waves using a surface structure designed to have different height distributions to focus the ultrasonic waves in a set pattern shape on the target surface.
