Facing the fact that the medicians are the front-line of this fight against the pandemia, we realized  that their integrity, security, but as well the necessity of achieving clear spoken messages from them is relevant. On the other hand, the possibility to have remote triage, with GPS and video-camera devices also may contribute to enable a safer environment. Nevertheless, taking into account that the same design may be used for patients and for the general community, we arrived to a modular design, in the sense, that the more complex one is suitable for the health personnel, and with less complexity for the patient, and even less complexity for the general community.

What it does

It is a helmet that has a modular structure: 1) For the medicians, it is enhanced with electroacoustic reinforcement and video/GPS tracking, so that the doctor may communicate with colleagues and with the patients, or the possibility to enable teletriage from the main health point. 2) For the patient, video tracking is no longer needed, and, 3) for the general community, the most basic configuration of the helmet enables them to walk safe and be in the outside world, with a device which protects them from the virus.

How we built it

The design starts from a standard helmet to which we add an electroacoustic system (miniature microphone + micro-loudspeakers),  that allows clarity in the doctor's voice; as well as buttons that activate lights for dark environments and a camera for photo and video. In addition, in order to optimize air flow and avoid saturation of particulate material in the filter, there is a ventilator with a filter in the back side of. In case the patient coughs or sneezes, the material that has just come out does not enter immediately to the filter. Finally, the use of antibacterial textiles, in order  to avoid contamination of the helmet, is utilized.

Challenges we ran into

The complexity of different communication protocols for enabling mutual interfacing between devices. To design a modular system that works for medical staff, patients and citizens with different levels of safety. The design of a product that enhances communication practitioner to practitioner as well as practitioner to patient. To reduce the rapid saturation and fast replacement of breathing filters due to the constant exposure to the virus.

Accomplishments that we are proud of

A system which may serve either for the medician, as well as for the patient, or even more for the general public. The design is modular, so that there is the possibility to easily switch between configurations depending on the risk level. A system that covers the need of practitioners such as: enhancement of communication, decreasing the replacement of filters by locating in the back side of the helmet and locating lights and cameras that can be controlled easily  by the practitioner.

What we learned

Before the project, we never thought about the existence of anti-viral textile, or the possibility that technology could enable the remote assistance to the doctor by Wi-FI, GPS devices. As well, the idea of implementing an electroacoustic reinforcement, so that the doctor speech may be enhanced in order to become an understandable message is also genuine from this team.

What's next for Modular Helmet with electroacoustic reinforcement

We want to expand our Modular Helmet to other areas, such as the reinforcement of speech for school teachers, or university professors (in the case that they have a problem with their voice), or even to entertainment, military purposes, and so on. In addition, due to the fact that this pandemia will be long until a vaccine is developed,  we pretend that the less complex version of the product (for citizens) helps to gradually resume daily activities in a safer way.
