Abstract
Tracking the health effects of microgravity on the human body is vital for continued space exploration. The adverse effects on the muscular and cardiovascular systems have chronic and immediate effects on astronauts' health. Biometric data like arterial pulse and muscle strength are important for early prevention and diagnostic care.
A skin-conforming force sensor can continuously monitor these biomechanical signals. Astronauts can also comfortably wear sensors for extended periods while performing mission tasks. The wearable sensors are fabricated via manual screen printing, which is ideal for manufacture on demand. The force sensor is composed of a piezoelectric film sandwiched between two electrodes. This array is then attached to the skin using a biocompatible adhesive. The electrodes are composed of a PEDOT: PSS ink, and the active layer utilizes PVDF-TrFE. To derive piezoelectric characteristics, the sensor is then poled using high voltage.
The scope of this research explored ink characterization and multiple printing methods. Different ink compositions for screen printing and direct ink writing were developed. Further research would integrate the sensor with post-processing circuits and data transmission via Bluetooth.
