India-based architecture practice Architecture Discipline is the latest team to devise a wearable option. Their sChoker, crafted from carbon fibre, integrates thermal sensors which identify the infrared radiations emanating from the temperature of those passing by. It will then let the wearer know if they are at a safe or dangerous distance using either a visual or audio signal – perhaps also with the added benefit of ensuring everyone stays away. ‘It is a symbol of unity,’ says Akshat Bhatt, principal architect at Architecture Discipline. ‘The need was to make it easily available and simple, for it to uphold privacy and anonymity and allow people to be socially "normal" and not "distant".’ The ergonomic circular ring design was a deliberate move to ensure the sensors could be mounted to cover a 360 degree angle. The neck, the straightest part of the body while moving, was the obvious place to wear it. The first carbon fibre prototype was made using 3D printing.
