Develop a vibration isolation system for lightweight automotive seats.

• Built and tested a piezoceramic-actuated vibration isolation system for a quarter-seat model.
• Experimentally-demonstrated a fivefold reduction in the isolation frequency of the quarter-seat test setup.
• Measured the transmissibility characteristics of a production-model car seat.
