Journal ArticleDOI
Highly ordered nanowire arrays on plastic substrates for ultrasensitive flexible chemical sensors
TL;DR: This work presents a scalable and parallel process for transferring hundreds of pre-aligned silicon nanowires onto plastic to yield highly ordered films for low-power sensor chips, and uses SiO2 surface chemistries to construct a 'nano-electronic nose' library.
Journal ArticleDOI
Graphene-based wireless bacteria detection on tooth enamel
Manu Sebastian Mannoor,Hu Tao,Jefferson D. Clayton,Amartya Sengupta,David L. Kaplan,Rajesh R. Naik,Naveen Verma,Fiorenzo G. Omenetto,Michael C. McAlpine +8 more
TL;DR: Graphene can be printed onto water-soluble silk, which permits intimate biotransfer of graphene nanosensors onto biomaterials, including tooth enamel, which is a fully biointerfaced sensing platform, which can be tuned to detect target analytes.
Journal ArticleDOI
3D printed bionic ears.
Manu Sebastian Mannoor,Ziwen Jiang,Teena James,Yong Lin Kong,K. Malatesta,Winston O. Soboyejo,Naveen Verma,David H. Gracias,Michael C. McAlpine +8 more
TL;DR: A bionic ear is generated via 3D printing of a cell-seeded hydrogel matrix in the precise anatomic geometry of a human ear, along with an intertwined conducting polymer consisting of infused silver nanoparticles, which enables readout of inductively-coupled signals from cochlea-shaped electrodes.
Journal ArticleDOI
Piezoelectric Ribbons Printed onto Rubber for Flexible Energy Conversion
TL;DR: Fundamental characterization of the ribbons by piezo-force microscopy indicates that their electromechanical energy conversion metrics are among the highest reported on a flexible medium, enabling a host of exciting avenues in fundamental research and novel applications.
Journal ArticleDOI
Enhanced Piezoelectricity and Stretchability in Energy Harvesting Devices Fabricated from Buckled PZT Ribbons
TL;DR: This work generates wavy piezoelectric ribbons on silicone rubber, a novel strategy for overcoming limitations in the integration of energy conversion devices which operate in stretching mode via reversible deformations in the wavy/buckled ribbons.
