Abstract: A number of variations may include a product comprising: an electrochemical device comprising an anode and a cathode, and at least one sensor comprising a plurality of strain sensing components and at least one temperature sensing component wherein each of the anode and the cathode comprises at least one strain sensing component comprising an optical fiber comprising at least one grating, wherein the at least one sensor is constructed and arranged to provide measurements that derive both state of charge and temperature of the anode and the cathode simultaneously.
