  • ELECTRO-MECHANICAL MASSAGE DEVICE AND WEARABLE MASSAGE APPARATUS
    Publication number: 20100056847
    Abstract: The invention relates to a massage device (1). The massage device (1) comprises a first support (32), a second support (30) and a deformable connector (36). The first support (32) has a massage face (34). The second support (30) has a protrusion (31) for accommodating an electrical coil (8). During use of the massage device (1), electrical coil 8 conducts an electrical current. First support (32) is provided with an electro-magnetic system (15) comprising permanent magnets (14, 24) or one or more electrical coils, magnetically conductible bodies or a combination thereof. First support (32) is connected to second support (30) by a deformable connector (36). As a result of electro-magnetic interaction a force indicated by an arrow (56) is exerted on protrusion (31). The first support (32) may be displaced relative to the second support (30).
    Type: Application
