The utility model discloses a multi-mode fusion touch fingertip module which comprises a supporting layer (107). The outer surface of the supporting layer (107) is provided with a proximity sense sensing layer (101) used for sensing the distance, a temperature site (102) used for sensing the temperature, a touch sense / slip sense sensing layer (103) used for sensing the touch sense, a control element (104), an electrode layer (105) used for transmitting signals and a force sensing layer (106) used for sensing the force. According to a three-dimensional force three-dimensional tactile sensing network, multi-mode sensor signals can be obtained, a multi-branch tactile neural network is constructed by using the signals, and a tactile fingertip module is formed, so that the shortages of two-dimensional tactile sensing can be made up, and three-dimensional characteristics of tactile sensing can be obtained; that is to say, richer haptic information such as output magnitude, direction, acting position, spatial distribution of force, dynamic force time sequence characteristics, spatial distribution of temperature and the like can be decoupled, various characteristics of the object are extracted, and the accuracy of object haptic recognition is improved.

This invention discloses a transparent high-precision touch-sensitive skin for robots and its fabrication method, belonging to the field of robot perception and human-computer interaction technology. The skin is designed with two architectures: one is a single-functional layer structure integrating a transparent mesh touch layer to achieve high-precision touch positioning; the other is a dual-functional layer structure with a superimposed transparent pressure-sensing touch layer, simultaneously achieving touch positioning and precise pressure quantization. This invention uses a fine metal mesh with a line width of 2-20 μm and a spacing of 300-600 μm as the sensing unit, achieving a positioning accuracy of ≤0.1 mm while ensuring ≥84% light transmittance. Reliable interlayer bonding, pressure conduction, and electrical isolation are achieved through a transparent optical adhesive layer of a specific thickness. This skin combines high transparency, high sensing accuracy, excellent flexibility, and environmental adaptability, and can be widely used in service robots, medical robots, and industrial robots on complex curved surfaces requiring visual tactile interaction.

An adaptive tactile feedback touchpad with customizable texture simulation adapts feedback to provide realistic, nuanced sensations associated with different textures by sensing touch input attributes, such as input location and force, and determining additional touch attributes, such as direction and velocity, from a time-series set of touch inputs. Touchpad haptic actuators implemented in one or more axes of a touchpad can be controlled with varying amplitudes (e.g., weights) to provide consistent tactile sensations regardless of the location and direction that a user touches and moves a finger on the touchpad. A haptic waveform can be selected, for example, based on the simulated texture and input velocity while a waveform amplitude can be determined based on input force, direction, and velocity. The haptic actuator(s) can be controlled by the selected waveform and determined amplitude to provide realistic tactile sensations regardless where the user interacts with the touchpad.
