Bone Speaker Process

Bone transformation

The bone audio speakers are a project that I worked on at SymbioticA over 2004-06. Bone is known to be piezoelectric, hence it has the capacity to be made to vibrate in response to an applied oscillating voltage. After an initially unsuccessful attempt in 2004, I worked with a Biomedical Engineering Honours student, William Wong, over 2006 to to realise the bone speakers. Using a laser interferometer (pictured below) we measured the nanoscale bone vibrations and managed to hear them using a stethoscope. I have published two papers about the conceptual framework of the work and process of making the speakers which can be accessed here.
