Abstract: The invention provides a three-dimensional force flexible tactile sensor and a fabrication method and a decoupling method thereof. The three-dimensional force flexible tactile sensor includes a first flexible layer, a porous elastic layer and a second flexible layer which are arranged in sequence. The first flexible layer is provided with a plurality of first electrodes. The second flexible layer is provided with a second electrode. The first electrodes and the second electrode are both clung to the porous elastic layer. The sensor not only can detect normal mechanical load, but also can measure the force tangent to the surface of the sensor, thereby realizing the detection of the three-dimensional force.

Abstract: Thin-film pressure sensors are disclosed herein. Such sensors include one or more electrodes in contact with a sensing material. As the sensor deforms the capacitance of the sensor varies and is measurable either between two electrodes of the sensor, or between the one electrode of the sensor and an electrode formed by the surface to which the sensor is applied, such as skin. The sensing material can be an ionic material such as an ionic composite including an ionic liquid.

Abstract: A pressure sensing apparatus which utilizes an electrolytic droplet retained between a first and second sensing electrode within a housing. Contact between the electrolyte droplet and the electrodes form electric double layers (EDL) having interfacial EDL capacitance proportional to interface contact area which varies in response to mechanical pressure applied to deform exterior portions of the housing. The electrolyte contains a sufficient percentage of glycerol to prevent evaporative effects. Preferably, the sensing electrodes are modified with depressions, hydrophilic and/or hydrophobic portions to increase central anchoring of the electrolyte droplet within the housing. The inventive pressure sensor provides high sensitivity and resolution which is beneficial to numerous applications, and is particularly well-suited for medical sensing applications.
