TLDR
An integrated skin prototype with embedded deformable sensors and attached suckers developed for the arm of an octopus inspired robot is presented.Abstract:
soft skin artefacts made of knitted nylon reinforced silicon rubber were fabricated mimicking octopus skin. A combination of ecoflex 0030 and 0010 were used as matrix of the composite to obtain the right stiffness for the skin artefacts. Material properties were characterised using static uniaxial tension and scissors cutting tests. Two types of tactile sensors were developed to detect normal contact; one used quantum tunnelling composite materials and the second was fabricated from silicone rubber and a conductive textile. Sensitivities of the sensors were tested by applying different modes of loading and the soft sensors were incorporated into the skin prototype. Passive suckers were developed and tested against squid suckers. An integrated skin prototype with embedded deformable sensors and attached suckers developed for the arm of an octopus inspired robot is also presented.read more

Soft-matter capacitive sensor for measuring shear and pressure deformation
TL;DR: A soft-matter sensor that measures elastic pressure and shear deformation that is embedded with fluidic parallel-plate capacitors is introduced and it is indicated that 2D shear and pressure deformation can be discriminated with approximately 500 μm and 5 kPa sensitivity.

Revealing bending and force in a soft body through a plant root inspired approach
TL;DR: In this paper, the authors used two tactile sensing elements, made of soft and stretchable materials, which conform to reversible changes in the shape of the body they are built in and follow its deformations.

The skin: an indispensable barrier
TL;DR: Changes in epidermal differentiation and lipid composition lead to a disturbed skin barrier, which allows the entry of environmental allergens, immunological reaction and inflammation in atopic dermatitis.

Tactile Sensing—From Humans to Humanoids
TL;DR: Tactile sensing, focused to fingertips and hands until past decade or so, has now been extended to whole body, even though many issues remain open, and various system issues that keep tactile sensing away from widespread utility are discussed.

Barrier Function of the Skin: “La Raison d'Être” of the Epidermis
TL;DR: More sophisticated understanding of epidermal barrier function will lead to more rational therapy of a host of skin conditions in which the barrier is impaired, current work has focused on developing a more physiologic mix of lipids for topical application to skin.
