Inconclusive and inconsistent results from existing haptic testing systems, e.g. for trackpads, which include rigidly mounted resistive load cells and accelerometers, prevent accurate results, especially in a high-volume production context. The use of a rigidly mounted sensor is unsuitable because a trackpad will generally be softer than the actuation system, whereby, when the haptic event is fired, the vast majority of the energy will be lost in the trackpad, while the sensor remains almost stationary. Accordingly, an improved test probe for a haptic device configured for mounting on a robotic arm, comprises: a contact tip configured for contacting the haptic device; a sensor configured for measuring a threshold force of the piezoelectric actuator device, and an haptic characteristic, e.g. acceleration, of a resulting haptic response thereof at a same time and a same location; and a compliant element configured for enabling the sensor to move relative to the haptic device.

The processor receives biometric parameters of the subject simultaneously with the scenario and analyzes the parameters in relation to the one or more high stress events. The analysis is used to reinforce psychological skills and mitigate long-term negative behavioral health outcomes associated with traumatic stress (e.g., PTSD).

This application discloses a tactile sensor and its fabrication method. The tactile sensor includes a tactile membrane, an optical window, a cavity, a deformation structure, and a capacitor structure. The cavity is enclosed by a cavity wall and two opposing openings at both ends. The two openings respectively house the tactile membrane and the optical window. The deformation structure is located within the cavity and is used to absorb energy from an external light source. Under photothermal action, it deforms, thereby displacing the tactile membrane to generate tactile stimulation that can act on a target object. The capacitor structure converts the tactile stimulation into an electrical signal for tactile information acquisition. This application utilizes the deformation structure to deform within a certain temperature range, thereby displacing the tactile membrane and converting light energy into tactile output. This avoids the dependence of traditional light-driven tactile devices on closed air cavities, gas expansion, and suspended light-absorbing sheets, improving the structural stability and driving efficiency of the tactile sensor and increasing its environmental adaptability.
