This wearable device is based on the naturally occurring self-defense mechanisms found in the Cactus (Opuntia Microdasys). Opuntia protects the user and informs others of a woman’s pregnancy. For instance, Opuntia can be employed as a safety belt in a vehicle. The majority of the seat belts for pregnant women don’t consider the belly, which is very unsafe and uncomfortable. Opuntia allows the user to wear the seatbelt normally, while preventing unwanted pressure from sudden stops. The device consists of three layers: the front, middle, and inner layer. The front layer has an embossed surface made out of visco-elastic polymer, which is an effective shock absorber. Moreover, it has a shielded, vibrating sensor that detects changes in the environment surrounding the user. The middle layer is a water or gel-type cushion that expands the impact of the shock. The inner layer is made of latex that relieves pain and has sensors that monitor the heart rate. Lastly, there are elastic bands in the front layer that can adjust to the changing size of the belly during pregnancy, while there are also supports in the back to help ease the weight of the stomach.
