Energy harvesting technology is still in its infancy. In a "Bending the Design Rules" presentation with voiceover, Dr. Markys Cain of the National Physical Laboratory describes one part of the solution--the materials science of piezo materials. The efficiency by which a piezo material may convert vibrational energy into useful electrical energy is described together with a description of the typical sources of energy found in the environment. Finally, the work of the Multifunctional Materials research group at the NPL that is focused on understanding measurement issues is presented.
