主 题：dual-mode pressure sensor homogeneous bonding all-in-one structure indoor body area network node elderly caregiving microsystem
摘 要：Pressure sensors are considerably important for continuous monitoring of human movement and the surrounding environment to construct a caregiving system for the elderly living *** challenge for pressure sensors that still remains is combining self-driven,comfort,and ***,an all-in-one conformal pressure sensor(ACPS) based on a homogeneous integrated triboelectric-piezoelectric hybrid sensor is *** ACPS has dual-mode sensing properties due to coupling triboelectrification and piezoelectric effect ensuring a stable response to various external ***-coated glass microspheres and polyacrylonitrile were uniformly filleted into the silicone rubber substrate using a hetero-doping method to create a stretchable electrode layer with flexible conformal characteristics and a piezoelectric layer with excellent piezoelectric properties,***,the triboelectric layer was fabricated using the same silicone rubber,allowing ACPS to be homogeneously bonded into an all-in-one structure with reliable *** allowed various functional layers to have outstanding interface characteristics and thus improve the electrical transmission *** developed ACPS had outstanding sensitivity(1.04 V/104Pa),high linearity(about 0.984),a wide measurement range(10–700 k Pa),and can accurately and continuously distinguish multiple ***,using a homemade signal processing circuit,ACPSs can be deployed in the human body and the room as indoor body area network *** successfully applied to the remote tracking of daily dynamic home life and the remote operation of small electrical equipment,these ACPSs can achieve real-time caregiving for the elderly living *** an application area desperately needed by society,this study envisions a caregiving system for the elderly living alone without violating personal privacy.
