Current soft surface electrodes have attracted more and more attention owing to their potential applications in the fields of biological signal monitoring, wearable human–machine interface and internet of things. The paper presents that soft dry electrode based on PDMS-CB conductive polymer is designed and fabricated to continuous, long-term, stable electrocardiogram (ECG) signal recordings which is conformal contact with the soft skin surface. The wearable electronic platform based on the soft dry electrode is built up to collect the ECG data. Integration of the soft dry electrodes with wearable electronic platform would improve the wearability and adaptability of the soft electrode in biological healthy monitoring which represents the future application in ubiquitous healthcare. Experiments have demonstrated that ECG data from the soft electrodes are recorded with PQRST wave which are similar to ECG data from Ag/AgCl gel electrodes. Meanwhile, robustness and stability of ECG signal are validated by the soft dry electrodes with different body actions.
