A distributed activation system for a unitary sheet of electrically conductive or insulative shape memory alloy having a sufficiently small section to limit the lateral flow of heat including at least one heating element disposed on the shape memory alloy sheet for locally heating an adjacent portion of the sheet such that the adjacent portion assumes a predetermined shape when activated to its threshold temperature. The activation system may be configured for shape memory alloy apparatus and related methods in combination with a control system for selec...
[ What is claimed is:] [1.]1. A method of making a distributed actuator array having a two-dimensional SMA sheet, the method comprising the methods of:a.) providing an insulating layer over the two-dimensional SMA sheet;b.) providing a distributed array of heaters over the insulating layer, each to selectively heat a respective portion of the two-dimensional SMA sheet;c.) providing electrically isolated feed lines for supplying current to each respective heater of the array;d.) providing an array of sensors for deriving angular deflection states of local...
