    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.

    Abstract: A low power consumption multi-contact micro electro-mechanical strain/displacement sensor and miniature autonomous self-contained systems for recording of stress and usage history with direct output suitable for fatigue and load spectrum analysis are provided. In aerospace applications the system can assist in prediction of fatigue of a component subject to mechanical stresses as well as in harmonizing maintenance and overhauls intervals. In alternative applications, i.e. civil structures, general machinery, marine and submarine vessels, etc., the system can autonomously record strain history, strain spectrum or maximum values of the strain over a prolonged period of time using an internal power supply or a power supply combined with an energy harvesting device. The sensor is based on MEMS technology and incorporates a micro array of flexible micro or nano-size cantilevers. The system can have extremely low power consumption while maintaining precision and temperature/humidify independence.
