ABSTRACT A wearable device for detecting human fall comprising a flexible electronic panel equipped with a first sensor, a polymeric substrate housing the flexible electronic panel and a belt facilitating the polymeric substrate and the first sensor to hold close to the human body, wherein the flexible electronic panel detects the human fall when the first sensor measures a movement of the human body exceeding a predetermined threshold value in three orthogonal directions and sends an alert message to a concerned individual. In another embodiment, a method of preparing a flexible polymer substrate comprising mixing at least 10 parts of a PDMS base in at least 1 part of a curing agent vigorously, removing air bubbles from the mixture, incubating the mixture for a predetermined period of time, wherein the mixture after incubation period gets hardened which is then processed to obtain a desired size and shape of the substrate.
