In various nations, there are several older members of the society who are need of help constantly.

Usually, older people do not have many people by their side when they face a medical emergency, and  due to their suffering, they cannot alert people using anything.

So, a device that is wearable/convinient to carry that allows its user to alert emergency contacts  immediately will be of great help in such conditions.

The device should be compact, wearable, convinient to use and there should be no delay in the  communication of the information.

The device can be in the form of a small locket/ring so that it can be used all the time, it will be a  revolutionary in the medical field and will many lives.
