Disclosed is a robust tactile sensor array that mimics the human fingertip and its touch receptors. The mechanical components are similar to a fingertip, with a rigid core surrounded by a weakly conductive fluid contained within an elastomeric skin. It uses the deformable properties of the finger pad as part of the transduction process. Multiple electrodes are mounted on the surface of the rigid core and connected to impedance measuring circuitry within the core. External forces deform the fluid path around the electrodes, resulting in a distributed pattern of impedance changes containing information about those forces and the objects that applied them. Strategies for extracting features related to the mechanical inputs and using this information for reflexive grip control.

A device usable as an applicator comb, comprising a collection of applicator teeth inserted into a tubular body (1) as supporting element, permitting liquid or gelatinous products to be applied precisely and economically, by having attached to the device a container or receptacle holding the treatment product. For hair and scalp treatment, the product enters the applicator teeth (2, 2I, 2II, 2III, 2IV, 2V. The product to be applied may cover all, only the sides or only the base of the applicator teeth, depending on whether the treatment is to be given on the totality of the hair and scalp, only on the hair, or on the base of the hair and in the scalp. Depending on the application, the tooth structure has a rigid core constituting the support for a permeable, peripheral cladding (13), or only a lateral cladding (12), without reaching the end.

An earplug of the type that includes a soft foam body (14) and a more rigid core (16) that stiffens the body during its insertion into the ear canal, is mass produced so the front end (30) of the stiff core cannot rub along the surface of the ear canal during insertion. The core is elongated and bonded to the body, and the core has a front end (30) that is recessed from the front end (36) of the body, so the soft foam material of the body prevents the front end of the core from contacting the ear canal. The earplug can be mass produced by extruding the soft foam through an extrusion head (42), around the cores, with a long core device having been cut into the cores and with the extrusion (52) cut at locations to leave foam material forward of each core front end.
