As illustrated in Fig. 4.1, the completed samples of the patterned conductive ink tracesTrace were subjected to both staticStatic and cyclicCyclic mechanical and electrical characterisation to evaluate their fundamentalFundamental properties and long-termLong-term performance. The staticStatic test serves as the initial baseline characterisation, performed prior to any mechanical loadingLoading. This test provides critical insight into the intrinsic properties of the printed conductive films in their undeformed state, offering a reference point against which subsequent changes, particularly those induced by cyclicCyclic stressStress, can be measured and analysed.
