Empower women through inconspicuous stealth technology. If there shall be an outrageous moment of despair from a potential sexual assault, take action through corresponding means. Inspired by the combination of merkins, venus flytrap carnivore plant and bear traps, the Surface Traptor is a concept to counter-balance unjust and outrageous attempts of these sort.
The Surface Traptor is a device activated by sEMG (surface electromyography). In the medical industry, sEMG are used for diagnosis, but this can could sourced towards the mechanism of setting the Surface Traptor. According to the “Functional Anatomy of the Pelvic Floor and Lower Urinary Tract” by Daniele Perucchini and John O.L. DeLancey, the pelvic floor can be the muscle in charge of triggering the device. Specifically, there could be three potential female pelvic muscles: the legator animuscle (ATLA), the puborectal muscle (PRM) and/or perineal body. According to Clare J. Fowler and David B Vodusek in their “Electrophysiology” work, they write that around 50mV could be considered as a good signal for the surface electromyography sensors, since their recordings are likely to give the best results. Ideally, the Surface Traptor should be made from the material Buckypaper, which unreliable sources –Wikipedia– 1/10 and potentially 500 times stronger than steel. Combine that with a sharpen edge, and that's what the Surface Traptor is.
However for the heart fainted and non-believers the activation could also take place wirelessly, through Wonkeun Youn and Jung Kim’s work, “Development of a Compact-size and Wireless Surface EMG”. They’ve developed a system that’s 37 * 17 mm2 and 19gs. With this wireless component, women could trigger the Surface Traptor through whichever other muscle they’d like to. After talking with Almudena, she helped me realize that calf activation could be a potential useful trigger interaction. Given to the use of calf muscles, it seemed that in a potential adverse situation, these could be a very convenient way of setting off the device.
