Abstract: A tactile sensor utilizes a magnet embedded in an elastomer and a magnetometer for measuring a strength of a magnetic field emitted by the magnet. The elastomer may include two layers, with a first layer having a lower modulus than the second layer. When two layers are used, the magnet can be positioned at an interface between the layers. The use of a softer outer layer increases the sensitivity of the sensor. Sensitivity can be further increased by including features or a pattern of features on the surface of the elastomer. The features, which can be similar to fingerprints on a human hand, are adapted to provide vibrational information caused by the surface roughness of a material. The sensor provides material characterization and can be used to identify the material in contact with the sensor. The sensor can be fabricated using molding techniques.

Abstract: Disclosed are a composition for use in photoelectronic component encapsulated, an encapsulation structure and a photoelectronic component. The composition includes 10%~70% of a photocurable monomer; 10%~70% of a monofunctional or trifunctional silicon-containing monomer; and 0.5%~10% of an initiator. The use of the silicon-containing monomer, on the one hand, because of the strong distensibility of Si—O—Si chain segment of self, provides a stress dispersing effect upon impact, reduces internal stress, and increases the mechanical performance of the organic encapsulation composition; and on the other hand, effectively increases the thermal performance and hydrophobicity of the organic encapsulation composition. Film packaging for use in the photoelectronic component may effectively increase the service life of the component.

Abstract: A method for relieving forward leaning during braking of a vehicle, a controller, and a vehicle. In the method for relieving forward leaning during braking, when a deceleration of the vehicle is less than a preset deceleration at a first moment at a final braking stage during forward traveling of the vehicle, a braking torque output by an electronic mechanical brake apparatus is controlled to be less than a braking torque indicated by a brake pedal stroke of the vehicle. Therefore, when the deceleration of the vehicle at the final braking stage is small, the deceleration of the vehicle can be further appropriately decreased by actively decreasing the braking torque output by the electronic mechanical brake apparatus, to relieve forward leaning caused by a sudden change of an excessively large deceleration of the vehicle at the final braking stage, and improve driving and ride comfort.
