| 1 | Polymeric foams for flexible and highly sensitive low-pressure capacitive sensors显示文摘Flexible low-pressure sensors(<10 kPa)are required in areas as diverse as blood-pressure monitoring,human–computer interactions,robotics,and object detection.For applications,it is essential that these sensors combine flexibility,high sensitivity,robustness,and low production costs.Previous works involve surface micro-patterning,electronic amplification(OFET),and hydrogels.However,these solutions are limited as they involve complex processes,large bias voltages,large energy consumption,or are sensitive to evaporation.Here,we report a major advance to solve the challenge of scalable,efficient and robust e-skin.We present an unconventional capacitive sensor based on composite foam materials filled with conductive carbon black particles.Owing to the elastic buckling of the foam pores,the sensitivity exceeds 35 kPa^(−1) for pressure<0.2 kPa.These performances are one order of magnitude higher than the ones previously reported.These materials are low-cost,easy to prepare,and display high capacitance values,which are easy to measure using low-cost electronics.These materials pave the road for the implementation of e-skin in commercialized applications. | Mickaël Pruvost Wilbert J.Smit Cécile Monteux Philippe Poulin Annie Colin | 2019 | npj Flexible Electronics2019，3，1： | 5 |

| 3 | Engineering polymer MEMS using combined microfluidic pervaporation and micro-molding显示文摘In view of the extensive increase of flexible devices and wearable electronics,the development of polymer microelectro-mechanical systems(MEMS)is becoming more and more important since their potential to meet the multiple needs for sensing applications in flexible electronics is now clearly established.Nevertheless,polymer micromachining for MEMS applications is not yet as mature as its silicon counterpart,and innovative microfabrication techniques are still expected.We show in the present work an emerging and versatile microfabrication method to produce arbitrary organic,spatially resolved multilayer micro-structures,starting from dilute inks,and with possibly a large choice of materials.This approach consists in extending classical microfluidic pervaporation combined with MIcro-Molding In Capillaries.To illustrate the potential of this technique,bilayer polymer double-clamped resonators with integrated piezoresistive readout have been fabricated,characterized,and applied to humidity sensing.The present work opens new opportunities for the conception and integration of polymers in MEMS. | Damien Thuau Cédric Laval Isabelle Dufour Philippe Poulin Cédric Ayela Jean-Baptiste Salmon | 2018 | Microsystems & Nanoengineering2018，4，1： | 0 |
