Tactile stimulating device with measurable tactile stimulating force and adjustable force frequency

Abstract

The invention relates to a tactile stimulating device with measurable tactile stimulating force and adjustable force frequency. The tactile stimulating device comprises an alternating current motor mechanism which is used for sending a pulse and driving an eccentric wheel to rotate, an elastic steel ruler mechanism for generating elastic deformation, an eccentric wheel mechanism for generating force data, and a probe mechanism which is used for generating a displacement in the vertical direction to change to stimulate the epidermis of a living organism, wherein the alternating current motor mechanism is fixedly connected with the eccentric wheel mechanism; the eccentric wheel of the eccentric wheel mechanism is closely attached to an elastic steel ruler of the elastic steel ruler mechanism; and the probe mechanism is fixedly arranged on the lower end surface of the elastic steel ruler mechanism. The tactile stimulating device is simple in structural design, high in integration degree and safe to work; an electromagnetic material covers the outer surface of an alternating current motor to form an electromagnetic shielding device, so that interference is basically eliminated, and the signal stability is high; by the adoption of a noninvasive mechanical stimulation mode, no wound can be caused in the use process; and as the frequency can be adjusted and the stimulating strength can be adjusted, the force action is stable, and the tactile stimulation within a relatively wide frequency range can be flexibly modulated.

Description

technical field [0001] The invention relates to the technical field of tactile force stimulation instruments, in particular to a tactile stimulation device with measurable tactile stimulation force and adjustable force frequency. Background technique [0002] The sense of touch is the feeling that the human body feels the weak contact force on the body surface. It is a non-sustained nerve discharge activity caused by the joint action of the pressure vertical to the body surface and the tangential force along the body surface on the tactile receptors. Different from the sense of pressure, the sense of touch is only the feeling of weak force on the body surface rather than pressure. The sense of touch is an important source of information for the human body to perceive the external force and obtain the texture properties of the contact object. In recent years, with the rise of virtual reality, human-computer interaction, medicine and health and other fields, research on tactil...

Problems solved by technology

At present, all kinds of existing tactile stimulation generating devices have the same problem. The force size and amplitude of the device are unmeasurable and uncontrollable, so there is a need for improvement or to be replaced by a new invention to realize the frequency, direction, size, and effect of force. Time can be detected synchronously
