Polymer micromachined multimodal tactile sensors

We present the design, fabrication process, and characterization of a multimodal tactile sensor made of polymer materials and metal thin film sensors. The multimodal sensor can detect the hardness, thermal conductivity, temperature, and surface contour of a contact object for comprehensive evaluation of contact objects and events. Polymer materials reduce the cost and the fabrication complexity...

Hybrid Tactile Sensing: Turning Garbage Bags into Tactile Sensors

In this paper, we introduce a new touch sensor design, which we refer to as hybrid tactile sensing. Hybrid tac-tile sensing combines the simplicity of analog touch sensing , which is widely used in electronic touch screens and touchpads, with the ability of shape discrimination of the array touch sensing, found in tactile sensors designed for robotics applications. We describe the construction ...

Tactile Sensors and Other Distributed Sensors with Minimal Wiring Complexity

This paper describes a tactile sensor design, allowing data acquisition from a sensor array using a single wire. The sensor is implemented as a filter. Sensor excitation changes filter characteristics, and the pressure profile can be recovered from the filter’s impulse response. The method is also applicable to sensor arrays for other scalar fields than pressure, such as heat, proximity, or rad...
