Accurately identifying edge balls in table tennis competitions remains a persistent challenge, frequently leading to delays, disputes, and compromised fairness owing to the inherent limitations of current detection technologies. To address this issue, we present a flexible polymer elastomer capacitor sensor that functions as a “Hawk-Eye system.” Owing to the intrinsic viscosity and toughness of the elastomer, the device is capable of real-time motion data acquisition and analysis across multiple target scenarios. The film-type capacitive sensor was fabricated from a styrene–isoprene–styrene block copolymer composite embedded with carbon nanospheres, exhibiting a high dielectric constant (6.54) and remarkable sensitivity (6.38 mV/N). Notably, this unique polymer-based film capacitor, which can be mass-produced via a one-pot synthesis method, offers both athletes and referees effective training guidance and real-time assistance during matches. Beyond table tennis, this work not only broadens the application of Hawk-Eye-like systems to smart sports monitoring and decision support, but also contributes to the advancement of big data analytics within the smart sports industry.
