Sensing electrode and method of fabricating the same

Abstract

A method of measuring signals from a surface. The method comprises: placing on the surface a flexible sensing device having an array of coated electrodes, wherein at least one electrode of the array is metallic and is at least partially coated by a polymer; and collecting signals from the sensing device.

What is claimed is: 
     
         1 . A sensing device comprising:
 an adhesive film formed with a plurality of openings and having a first side and a second side, wherein said first side is attachable to a skin; and   an array of dry electrodes screen-printed on said second side of said film, each electrode having a sensing portion exposed by an opening of said plurality of openings.   
     
     
         2 . The device of  claim 1 , wherein said electrode comprise a conductive carbon ink. 
     
     
         3 . The device of  claim 1 , wherein said adhesive film is a double-sided adhesive film. 
     
     
         4 . The device of  claim 1 , wherein said electrodes are dry. 
     
     
         5 . The device of  claim 1 , comprising an electrical coupler configured for connecting said electrodes to a measuring device. 
     
     
         6 . The device of  claim 5 , wherein said electrical coupler is a zero-insertion-force (ZIF) coupler. 
     
     
         7 . The device of  claim 5 , comprising said measuring device. 
     
     
         8 . The device of  claim 7 , wherein said measuring device is configured for measuring EMG signals. 
     
     
         9 . The device of  claim 7 , wherein said measuring device is configured for measuring EEG signals. 
     
     
         10 . The device of  claim 7 , wherein said measuring device is configured for measuring ECG signals. 
     
     
         11 . The device of  claim 7 , wherein said measuring device is configured for measuring EOG signals. 
     
     
         12 . A method of measuring signals from a skin, the method comprising:
 placing on the skin a sensing device; and   collecting signals from said sensing device;   wherein said sensing device comprises:   an adhesive film formed with a plurality of openings and having a first side and a second side, wherein said first side is attached to the skin; and   an array of dry electrodes screen-printed on said second side of said film, each electrode having a sensing portion exposed by an opening of said plurality of openings.   
     
     
         13 . The method of  claim 12 , wherein said electrode comprise a conductive carbon ink. 
     
     
         14 . The method of  claim 12 , wherein said adhesive film is a double-sided adhesive film. 
     
     
         15 . The method of  claim 12 , wherein said electrodes are dry. 
     
     
         16 . The method of  claim 12 , comprising an electrical coupler configured for connecting said electrodes to a measuring device. 
     
     
         17 . The method of  claim 12 , wherein said signals comprise EMG signals. 
     
     
         18 . The method of  claim 12 , wherein said signals comprise EEG signals. 
     
     
         19 . The method of  claim 12 , wherein said signals comprise ECG signals. 
     
     
         20 . The method of  claim 12 , wherein said signals comprise EOG signals.
