A Hybrid Low Power Biopatch for Body Surface Potential Measurement

---

Abstract—This paper presents a wearable biopatch prototype for body surface potential measurement. It combines three key technologies,includingmixed-signalsystemonchip(SoC)technology, inkjet printing technology, and anisotropic conductive adhesive(ACA)bondingtechnology.Anintegralpartofthebiopatchisa low-powerlow-noiseSoC.TheSoCcontainsatunableanalogfront end, a successive approximation register analog-to-digital converter, and a reconfigurable digital controller. The electrodes, interconnections,andinterposerareimplementedbyinkjet-printing the silver ink precisely on a flexible substrate. The reliability of printed traces is evaluated by static bending tests. ACA is used to attach the SoC to the printed structures and form the flexible hybridsystem.Thebiopatchprototypeislightandthinwithaphysical size of 16 cm × 16 cm. Measurement results show that low-noise concurrentelectrocardiogramsignalsfromeightchestpointshave been successfully recorded using the implemented biopatch.

Index Terms—Active cable, anisotropic conductive adhesive (ACA), biopatch, body surface potential, inkjet printing, system on chip (SoC), wearable device.
