Abstract: Herein disclosed is a method of printing a 3D freeform structure in an embedding medium. The method includes providing an ink composition in a nozzle, wherein the ink composition includes a thermoplastic, a non-thermoplastic, a thermally degradable polymer, and/or a thermosensitive polymer, dissolved in a solvent; dispensing the ink composition through a nozzle into the embedding medium to precipitate a printed structure from the ink composition, wherein the ink composition exits from the nozzle directly in the embedding medium; and maintaining the printed structure in the embedding medium until the immersion precipitation is completed for forming the 3D freeform structure. A system operable to carry out the method is also disclosed. The system includes a syringe coupled to a nozzle.

Abstract: There is provided a method of forming a thin film-based microfluidic electronic device. The method includes: providing a first elastomeric thin film layer on a substrate; depositing a first elastomer on the first elastomeric thin film by direct ink writing to form an elastomeric structure configured to define a microfluidic channel on the first elastomeric thin film layer; providing a second elastomeric thin film layer over the elastomeric structure to cover the microfluidic channel; providing a sacrificial layer on the second elastomeric thin film; depositing liquid metal into the microfluidic channel to form a conductor in the microfluidic channel; and electrically connecting the conductor to an electronic component. The thin film-based microfluidic electronic device is a tissue or skin adhesive sensor including a skin adhesive acoustic device.
