Physical Quantities

We have developed a flexible tactile sensor array capable of sensing physical quantities, e.g. force and temperature with high-performances and high spatial resolution. The fabricated tactile sensor consists of 8 × 8 force measuring array with 1 mm spacing and a thin metal (copper) temperature sensor. The flexible force sensing array consists of sub-millimetre-size bar-shaped semi-conductor strain gage array attached to a thin and flexible printed circuit board covered by stretchable elastomeric material on both sides. This design incorporates benefits of both materials; the semi-conductor's high performance and the polymer's mechanical flexibility and robustness, while overcoming their drawbacks of those two materials. Special fabrication processes, so called “dry-transfer technique” have been used to fabricate the tactile sensor along with standard micro-fabrication processes.

Properties Of Materials

Methylsilsesquioxane (Me-SSQ) was incorporated into cyanate ester resin (CE) to obtain organic-inorganic hybrids with better dielectric properties in this study. First, methyltriethoxysilane was hydrolyzed and condensed to synthesize Me-SSQ. Then several Me-SSQ/CE hybrids containing different contents of Me-SSQ were prepared. The effect of Me-SSQ content on the dielectric and hot/wet properties of materials was investigated. Results showed that the Me-SSQ/CE hybrid containing 20wt% of Me-SSQ shows a dielectric constant of 2.78, which is much lower than the pure CE resin. At the same time, the dielectric loss of the Me-SSQ/CE hybrids was slightly increased (tanδ<0.006). It indicates that Me-SSQ/CE hybrid is a promising matrix materials for high-performance printed circuit board (PCB).
