    • A housing (50) is placed on skin of a subject, and draws at least a portion of the skin within at least a part of the housing. The housing includes at least first and second support structures (34), placed in contact with a surface of skin surrounding the portion of the skin, the first support structure having a first concave surface (153) and the second support structure having a second concave surface (153) that faces the first concave surface. The apparatus includes one or more first ultrasound transducers (160) coupled to the first support structure and one or more second ultrasound transducers coupled to the second support structure. The apparatus also includes a control unit which drives the first and second ultrasound transducers to induce an implosion wave in a target region of the skin. Other embodiments are also described.
    • 将壳体(50)放置在受试者的皮肤上,并且在壳体的至少一部分内吸取皮肤的至少一部分。 壳体包括至少第一和第二支撑结构(34),放置成与围绕皮肤部分的皮肤表面接触,第一支撑结构具有第一凹面(153),第二支撑结构具有第二凹面 面(153)面向第一凹面。 该装置包括耦合到第一支撑结构的一个或多个第一超声换能器(160)和耦合到第二支撑结构的一个或多个第二超声换能器。 该装置还包括控制单元,其驱动第一和第二超声换能器以在皮肤的目标区域中引起内爆波。 还描述了其它实施例。

    • Apparatus (20) is provided comprising a skin-application portion (40), configured to move across skin of a subject. At least one acoustic element (50) is coupled to the skin-application portion (40) and configured to be placed in acoustic contact with the skin, and configured to apply ultrasound energy to the skin. The apparatus (20) additionally comprises circuitry configured to generate a current responsive to motion of the skin-application portion (40); and a control unit (10), which is configured to receive the current, to determine, responsive thereto, whether the skin-application portion (40) is moving with respect to the skin, and to drive the acoustic element (50) to apply the ultrasound energy to the skin responsive to determining that the skin-application portion (40) is moving with respect to the skin. Other embodiments are also described.
    • 提供了一种设备(20),其包括皮肤应用部分(40),其构造成移动穿过受试者的皮肤。 至少一个声学元件(50)耦合到皮肤施加部分(40)并且被配置为与皮肤声学接触,并且被配置为向皮肤施加超声波能量。 所述装置(20)还包括经配置以响应于皮肤施加部分(40)的运动产生电流的电路; 以及控制单元(10),其被配置为接收电流,以响应于此来确定皮肤应用部分(40)是否相对于皮肤移动,并且驱动声学元件(50)施加 响应于确定皮肤施加部分(40)相对于皮肤移动,对皮肤的超声能量。 还描述了其它实施例。
