Skea, the world’s first Smart Kegel Exercise Aid (SKEA), allows players to control their game by simply squeezing their pelvic muscles. Put inside body, Skea reads vaginal contraction with embedded pressure sensor and syncs with smart phones. Thus, the boring but crucial pelvic muscle training for women is turned into an engaging video game, which is carefully designed and paced to deliver optimal effects. Skea also vibrates when squeezed to deliver biofeedback.
