Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like figure 1 As shown, the flexible patch-type sensing and driving integrated device in this embodiment includes alternately stacked sensing and driving layers 1 and elastic electrode layers 2, and the bottommost and topmost layers are both elastic electrode layers 2. In addition to the elastic electrode layer 2 on the top layer, an insulating protective layer 3 is also provided.

[0033] The flexible chip module can be stacked with multiple layers (that is, the number of layers of the sensing driving layer 1 is greater than 2, and the sensing driving layer 1 and the elastic electrode layer 2 are stacked), and only the upper and lower protective layers 3 are covered on the outermost layer. The output force of this driver module or the sensing range of the sensor can be multiplied by stacking layers. The sensor-driving integrated devic...

Abstract

The invention discloses a flexible patch type sensing and driving integrated device, comprising sensing and driving layers and elastic electrode layers, which are alternatively laminated, and the bottom layer and the top layer are the elastic electrode layers, and the sensing and driving layers are dielectric elastomer films. The sensing and driving integrated device of the invention is simple in structure and easy to realize. As the sensing and driving layers and the elastic electrode layers are alternatively laminated according to the need, the deformation of the dielectric elastomer films caused by an external force is magnified, so that variable quantity of capacitance is increased, and the effects of increasing the sense measuring range and improving drive capability are achieved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a flexible patch type sensing and driving integrated device. Background technique [0002] Sensors and drives (actuators) are widely used in production and life and occupy an extremely important position. As a sensing element, a sensor is an important medium for people to obtain information. Flexible patch type, force or displacement sensor is a device that senses external tiny force or displacement information through the sensing element and converts it into an electrical signal. It plays an extremely important role in many engineering fields. For example, tactile sensors on human prosthetics, force feedback sensors for wearable devices, micro flow channel control (infusion tube control) in biomedicine, etc. The driver (actuator) is a kind of driving element, which will produce corresponding deformation or functional response after being stimulated by the outside world ...
