An Implantable Low-cost Multilayer Screen-printed Carbon Thick-film Strain Sensor
نویسندگان
چکیده
We present a rapid low-cost process for fabrication of screen-printed carbon thick-film strain sensors with 0.012% strain resolution. The sensors are suitable for implantation and designed specifically for strain or fullness measurements of the skin and bladder, respectively. Thick-film carbon paste sensors are screen-printed using an etched brass screen onto polydimethylsiloxane (PDMS) and encapsulated by a second layer of PDMS. This method can quickly produce multilayered devices by superposition of different screen printable materials. Single strain gauge devices as well as arrayed elements have been fabricated and tested using a latex balloon model of a bladder.

CO2 Selective Potentiometric Sensor in Thick-film Technology
A potentiometric sensor device based on screen-printed Nasicon films was investigated. In order to transfer the promising sensor concept of an open sodium titanate reference to thick film technology, "sodium-rich" and "sodium-poor" formulations were compared. While the "sodium-rich" composition was found to react with the ion conducting Nasicon during thermal treatment, the "sodium-poor" refere...
