Wearable sensor arrays enable spinal monitoring by tracking the critical muscular deformation, while the inter\u2010channel discrepancies within a sensor array usually leads to compromised accuracy in deformation mapping. Herein, we report a graphene\u2010based piezoresistive sensor array with minimized inter\u2010channel discrepancy (4.12% difference in baseline resistance across 8 channels) for spinal monitoring. The high inter\u2010channel consistency is achieved through a printing\u2010and\u2010transfer methodology employing photo paper as the intermediate substrate, which overcome the intrinsic incompatibility between graphene dispersion and stretchable polydimethylsiloxane (PDMS) substrate for homogeneous film deposition. Moreover, propylene glycol (PG) is applied as the ink\u2010engineering additive, which not only improve the printability of graphene dispersion, but also enable a high\u2010yield film transfer from photo paper to PDMS substrate through forming an interim layer at the graphene\u2010photo paper interface. For spinal kinetics monitoring, the sensor array could differentiate 6 trunk postures with a classification accuracy of 95.4% using machine learning algorithm. This work provides a scalable platform for daily spinal health tracking, enabling disease prevention and rehabilitation monitoring.<\/jats:p>","DOI":"10.1002\/smll.75826","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T08:28:55Z","timestamp":1790324935000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Propylene
