A method of making a stretchable transducer is disclosed. The method includes placing a polymer solution having a concentration (C) in an injectable vessel having an electrically conductive ejection port, applying a voltage (V) between the ejection port and an electrically conductive collection plate a predetermined distance away from the ejection port, ejecting the polymer solution from the injectable vessel at a flow rate (FR), thereby generating a fibrous material having a considerable -phase on the collection plate due to electrospinning, removing the fibrous material from the collection plate, depositing conductive electrodes on top and bottom surfaces of the removed fibrous material, thereby generating a transducer, and simultaneously optimizing formation of -phase of the fibrous material and yield of the transducer based on unwanted electrical current leakage between deposited electrodes on the top and bottom surfaces based on C, V, and FR.
