Abstract:
A device for detection of a defined relative position of a first, movable means, relatively a second, fixed means and including a sensor (1) arranged at least at one of the first and second means which sensor is provided with a pressure sensing means (CCM). The sensor (1) gives rise to an electric detector signal, which indicates whether the defined relative position has been taken. The sensor (1) is also provided with a closed cavity (13) which communicates with a pressure sensing means (CM) and with means (14/36/45) to momentarily limit the volume of the cavity and thereby create a pressure pulse adapted to activate the pressure sensing means of the sensor. The detector device includes means to convert the pressure pulse to a detection signal to detect the defined relative position.
Abstract:
Embodiments of the present disclosure describe a tactile sensor comprising an elastomeric membrane having a channel formed therein, a liquid conductive material located in the channel, and electrodes electrically connected to the liquid conductive material, sufficient to form a stretchable electronic tactile sensor, wherein the stretchable electronic tactile sensor can be stretched over 50% in at least two axial directions from a resting state of the stretchable electronic tactile sensor. Embodiments further describe a method of fabricating a tactile sensor comprising providing a mold for fixing a plurality of filaments in parallel on a first plane and on a second plane; casting a curable material into the mold; curing the curable material to form a membrane; extracting the plurality of filaments from the membrane to form microfluidic channels in the membrane; and functionalizing the membrane by introducing a conductive liquid into the microfluidic channels of the membrane.
