The PosturAroma Necklace is perhaps one of the more unusual ways to increase a woman's security as she walks the mean streets of an urban sitting. Foregoing the belief that there is safety in numbers as well as carrying around a legal weapon such as pepper spray, the PosturAroma Necklace focuses on improving the wearer's posture to ensure she walks more confidently, which supposedly lessens the chances of an attack.

Created by Akarsh Sanghi, Shinichiro Ito and Laura Mul from the University of Applied Sciences of Amsterdam, the PosturAroma Necklace is a response to MediaLAB Amsterdam's recent challenge to develop an intervention that improves women’s safety in public spaces. It essentially squirts an unpleasant scent when it detects a downcast demeanor.
