Piezoelectric sensor car seat monitors respiration, heart rate

Faurecia‘s “Active Welness” car seat monitors respiration and heart rate with embedded piezoelectric sensors.  The goal is to detect driver stress or alertness.  When low energy is detected, the seat responds with specific massage patterns and air flow through the ventilation system.  The non-contact sensors were developed by Hoana Medical.  Combined with advanced algorithms and signal processing, Faurecia claims that they can accommodate noise and vibration from the moving vehicle without compromising effectiveness.
