a Comparison of the working principles between the RigiScan and WARM systems. The RigiScan employs a two-step process for measuring penile tumescence and rigidity. In contrast, the WARM system utilizes two strain-sensing rings with different elastic moduli for these measurements. b Schematic of the WARM system. c Block diagram of the WARM system, which includes a dual-ring sensor for penile tumescence and rigidity assessment, a flexible printed circuit for signal acquisition, processing and wireless transmission, and a terminal for data display and analysis. d Optical image of the WARM system
