Partitalia srl, offers the “Close-to-me” and “Vita,” two wearable personal safety devices. The “Close-to-me device can be worn by two or more people to monitor social distancing based on a variable distance that can be set according to directives and regulations. Based on radio frequency technology, it creates a non-invasive, low frequency radio bubble around a person. A sound and vibration warns wearers when the set distance is not respected. Moreover, through simple adaptations, the device can be used to control accesses and detect presences.
