The latest in his Pulse series of heartbeat-synched light works, Rafael Lozano-Hemmer’s Pulse Topology premieres at Kansas City’s Kemper Museum of Contemporary Art. For the first time, the Mexican-Canadian artist integrated touchless photoplethysmography (PPG) sensors that use computer vision to detect visitors’ heartbeats. Another first: the use of LED filament light bulbs that lower the installation’s energy footprint while allowing for greater scale—instead of 100–300 bulbs, Pulse Topology is made of 3,000.
