Piezoelectric properties of aligned collagen membranes [PDF]
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2013 AbstractElectromechanical coupling, a phenomenon present in collagenous materials, may influence cell–extracellular matrix interactions. Here, electromechanical coupling has been investigated via piezoresponse force microscopy in transparent and opaque membranes consisting of helical‐like arrays of aligned type I collagen fibrils self‐assembled from ...

On the Piezoelectric Properties of Tourmaline
Physics, 1933 Oscillating piezoelectric plates of different frequencies have been made from California and South African Tourmaline. These plates have a frequency response of approximately 3770 kc per millimeter of thickness. The temperature coefficient for both specimens was found to be negative and is about 35.5 parts per million per degree centigrade for the ...
