It is the object of the present invention to provide a device for daily personal use which protects via pressure-relief and immediately alerts the user (e.g. private persons or hospital staff) as to undesirable effects of one or more body parts. The invention is a personal assistive device, which enables patients to be subjected to complicated hospital-monitoring in their homes with no external assistance at any time. This is achieved according to the present invention with an appliance for measuring pressure changes wherein the appliance comprises: one or more pressure-relieving and shock-absorbing regions which comprise(s) liquid and/or air tight pads, the pads containing liquid, gel, gas or a solid, and where the regions are in communication with each other; one or more RFID tags positioned in direct connection with the pressure-relieving and shock-absorbing regions for measuring both static and dynamic pressure changes in the pressure-relieving and shock-absorbing regions. The invention further relates to a system comprising the appliance and a user-feedback device. |
