The invention relates to a device comprising a flexible water-resistant housing body (2) containing a base plate (5), a power battery (6), a vibration-emitting motor (7), and at least two pressure sensors (8), as well as an antenna (3) for wireless connection between the device (1) and a smartphone or other electronic apparatus suitable for having installed a particular software, in the form of an app, which allows the operation of the device to be controlled. The housing body (2) is formed by two parts, a substantially oval main part (2a) and a secondary part (2b) in the form of an elongate flexible appendage containing the antenna (3). The main part (2a) of the housing body (2) houses a case (4) divided, in turn, into two halves, and in which the base plate (5), power battery (6) and vibration-emitting motor (7) are connected. The two flexible laminar pressure sensors (8) are incorporated outside of the case (4). The antenna (3) is inserted into the secondary part (2b) and housed in a plastic sheath (9). The wireless connection is by means of Bluetooth.Comprende un cuerpo envolvente (2), flexible y resistente al agua, en cuyo interior figura una placa base (5), una batería de alimentación (6), un motor (7) que emite vibraciones y como mínimo dos sensores de presión (8), así como una antena (3) de conexión inalámbrica entre el dispositivo (1) y un smartphone u otro aparato electrónico apto para incorporar instalado un software específico, en forma de APP, que permite el control de su funcionamiento. El cuerpo envolvente (2) está constituido por dos partes, una parte principal (2a), de configuración sensiblemente ovalada, y una parte secundaria (2b) en forma de apéndice alargado y flexible y en cuyo interior incorpora la antena (3). La parte principal (2a) del cuerpo envolvente (2) aloja una carcasa (4) dividida, a su vez, en dos mitades, donde se acoplan la placa base (5), la batería de alimentación (6) y el motor (7) que emite vibraciones.
