Characterization of Bio-Inspired Synthetic Hair Cell Sensors

摘要: Recently, researchers at Virginia Tech have developed biologically-inspired hair cell sensors that utilize the transport mechanism between cells to sense a variety of physical inputs. The consist hair-like, hydrogel-supported structure is encapsulated in lipid bilayer membrane. membrane itself capable producing change capacitance when excited, which measured by electrodes mounted base cell. This paper presents results modeling dynamic response synthetic for boundary conditions and non-contact excitation methods so can be related electrical output sensor. A finite element analysis performed rigid mounting conditions, then altered account varying degrees stiffness medium hair. model subsequently validated using high-speed imaging techniques closed-form solution. used characterize behavior sensor due excitation, such as excitation.
