A highly adhesive flexible strain sensor based on ultra-violet adhesive filled by graphene and carbon black for wearable monitoring
摘要： Ensuring the accuracy of signal detection under repeated deformation is a challenge for ?exible sensor reported in recent years, and achieving reliable adhension between the sensor and substrate is a key factor. Here, this article reported a highly adhesive ?exible strain sensor based on ultra-violet adhesive ?lled by modi?ed graphene and carbon black for wearable monitoring. This strain sensor with a typical resistive behavior shows gauge factor calculated at 0～10% strain is 2.1. It exhibits short curing time (～1 h), fast response (～40 ms), excellent adhesive strength (4500 kPa), and adhesiveness to various bending surfaces. Furthermore, this strain sensor can be directly prepared on elastic columns and rubber gloves, and exhibits excellent performance in three-dimensional force detection and writing gesture recognition. The ability of adhesive conformability to arbitrary and complex surfaces shows that the strain sensor has broad application prospects in wearable devices.

Laser treatment surface: An innovative method to increase the adhesive bonding of ENF joints in CFRP
摘要： Recently, many studies showed the opportunity to use a CO2 laser for treating the surfaces for structural bonding. In this work, a study on the effectiveness of a laser texturing on ENF bonded joints made with CFRP and epoxy adhesive has been developed. The experimental results showed that the use of this technology allows obtaining mechanical resistances of the bonded joints higher than 80% compared to untreated ones. Furthermore, a numerical model is proposed to forecast the response of the ENF specimens, and the numerical results are in good agreement with the experimental ones. This work represents a basis for the development of an innovative approach to design the laser texturing as a function of the applied stress.
