Fully printed flexible and disposable wireless cyclic voltammetry tag
A disposable cyclic voltammetry (CV) tag is printed on a plastic film by integrating wireless power transmitter, polarized triangle wave generator, electrochemical cell and signage through a scalable gravure printing method. By proximity of 13.56 MHz RF reader, the printed CV tag generates 320 mHz of triangular sweep wave from +500 mV to -500 mV which enable to scan a printed electrochemical ce...
متن کاملCapacitive Micromachined Ultrasonic Transducer Technology for Medical Ultrasound Imaging
Capacitive micromachined ultrasonic transducer (cMUT) technology has been recognized as an attractive alternative to the more traditional piezoelectric transducer technology in medical ultrasound imaging for several years now. There are mainly two reasons for the interest in this technology: Micromachining is derived from the integrated circuit technology and therefore shares the well-known adv...

متن کاملA Flexible Ultrasound Transducer Array with Micro-Machined Bulk PZT
This paper proposes a novel flexible piezoelectric micro-machined ultrasound transducer, which is based on PZT and a polyimide substrate. The transducer is made on the polyimide substrate and packaged with medical polydimethylsiloxane. Instead of etching the PZT ceramic, this paper proposes a method of putting diced PZT blocks into holes on the polyimide which are pre-etched. The device works i...
متن کاملInkjet printed flexible antenna on textile for wearable applications
We report a direct write inkjet printing technique for fabricating a flexible antenna on textile for use in smart textile applications such as wearable systems (Rienzo et al. 2006). The complete antenna was deposited entirely using inkjet printing. The inkjet printed antenna is based on a half wavelength dipole antenna offering a planar structure and acceptable size. The printable silver nanopa...
