The Langzhi Digital Care & Heating Mat combines real-time vital sign tracking with the added comfort of a graphene heating layer to provide warmth to the user. The Digital Care Heating Mat uses Ballistocardiogram signals to track heart rate, REM Sleep data, body movement and blood pressure and build up a health score over time using algorithms in the supported application (available on Android and iOS). The device itself is made up of layers, consisting of fire resistant outer fabric which encapsulates internal fire resistant sponge to add a cushion layer, BCG sensors, and a graphene heating element.
