This application discloses a tactile sensor, a detection method for a touch event, a sensing device and a robot, and belongs to the field of sensor design. The tactile sensor includes: a sensing unit, an elastomer support housing and a base; the sensing unit is disposed in an inner cavity enclosed by the elastomer support housing and the base; and the sensing unit includes at least two light sources, a photo detector and a reflector, where the photo detector is disposed on base, the at least two light sources are disposed around the periphery of the photo detector on the base, and the reflector is disposed at the top of an inner cavity of the elastomer support housing. By adopting the combination of a plurality of light sources and one photo detector, the number of photo detectors for use is reduced, so that the volume of the tactile sensor is reduced.

Tactile sensor equipped with multiple light sources and a photo detector, sensing device and robot having the same

This application discloses a conductive paste, a preparation method thereof, and a preparation method of a conductive film using the conductive paste. The conductive paste comprises: a thermoplastic polyurethane, conductive particles, and an organic solvent, the thermoplastic polyurethane and the conductive particles being proportionally mixed in the organic solvent, and the thermoplastic polyurethane being dispersed in the form of particles among the conductive particles. A thermoplastic polyurethane elastomer is used as a binder, and the conductive particles are mixed in the organic solvent containing the thermoplastic polyurethane elastomer. The conductive particles ensure the conductivity of the conductive film prepared using the conductive paste. The thermoplastic polyurethane has strong adhesion ability, and is suitable for use on the surface of most substrates, to form a conductive film with good adhesion and no cracking.
