What is a smart erection ring?
A smart erection ring is a constriction ring with sensors built in. The FirmTech TechRing keeps the doctor-designed peno-scrotal shape and adjustable hook-and-loop strap of FirmTech's other rings, and adds a small sensor module that connects over Bluetooth.
During sex it measures firmness, quality and duration. Overnight, it records the count, strength and length of nighttime erections. FirmTech explains why that matters: those erections happen without arousal, so they are a clean read of blood flow, and the small arteries in the penis can show changes before larger ones do. FirmTech calls the TechRing the first smart wearable for the penis, and says it was designed with leading urologists.
