Abstract: A wearable haptic device includes (a) substrate having provided thereon a fastener (e.g., adhesive) for attachment to a user; (b) one or more EMP transducers attached to the substrate, such that a mechanical response in each EMP transducer may provide a haptic response of sufficient magnitude to be felt by the user; and (c) control circuit controlling the vibration frequency, the time of operation and the duration for each activation of the EMP transducer. The wearable haptic device may include a wireless communication circuit (e.g., Bluetooth transceiver) for receiving message from an external device (e.g., smartphone). The control circuit interprets message received and according to the interpreted message provides an electrical stimulus to cause the mechanical response of the EMP transducer. The EMP transducer may also serve as a sensor, such that a mechanical stimulus on the EMP transducer provides an electrical response that is detected by the control circuit.

Abstract translation: 可穿戴的触觉装置包括（a）在其上设置有用于附接到使用者的紧固件（例如粘合剂）的基底; （b）附接到基底的一个或多个EMP传感器，使得每个EMP换能器中的机械响应可以提供足以使用户感觉到的足够大的触觉响应; 和（c）控制电路，控制振动频率，操作时间和每个激活EMP传感器的持续时间。 可穿戴式触觉装置可以包括用于从外部设备（例如，智能手机）接收消息的无线通信电路（例如，蓝牙收发器）。 控制电路解释所接收的消息，并且根据解释的消息提供电刺激以引起EMP传感器的机械响应。 EMP传感器还可以用作传感器，使得EMP传感器上的机械刺激提供由控制电路检测到的电响应。
