Whose Scalpel 2.0 is an audio-visual art performance that explores the intersection of technology and sensory perception. In this piece, the artist's cardiac MRI data are presented through technological devices, highlighting the progression of medicine and its cultural implications. During the live performance, the artist lets real time heart rate data from the artist, a dancer, and the audience influence the presentation and experience of images and sounds. This sensor-based interactive design fosters a multilayered perception of the body, prompting contemplation on body concepts and technology's role in our lives.
