Fabrication, Design and Application of Stretchable Strain Sensors for Tremor Detection in Parkinson Patient

Due to increasing demand for wearable health monitoring devices, stretchable electronics have developed rapidly in recent years. For human motion detection, strain sensors must be highly stretchable, sensitive, and durable. Another important factor is low-cost fabrication. As such, the sensors in this research were made of carbon nanotubes (CNTs) and graphene in Polydimethylsiloxane (PDMS) using a solution casting method. In order to improve bending sensitivity, slits were created on the sensor surfaces. The strain sensors were placed on an index finger in order to detect and monitor the hand tremors of Parkinson’s patients. Furthermore, a wearable glove system with hardware components including an Arduino Nano controller, stretchable strain sensors, a Real Time Clock (RTC) Module, and a Micro SD card Adapter was developed for practical use in everyday life.
