Description

The Sensit Wearable reduces the time-to-market for new electrochemistry-based wearable sensors. Wearable, flexible electrochemical sensors, for instance integrated on the epidermis, can be used to measure non-invasively metabolites and electrolytes for various biomedical applications.

Imagine applications like:

  • Continuous Glucose Monitoring
  • Sweat analysis for athletes
  • Moleculair biomarkers

The Sensit Wearable supports most common electrochemical techniques, including Cyclic Voltammetry, Square Wave Voltammetry and Impedance Spectroscopy (FRA/EIS). The Sensit Wearable runs autonomously for hours up to weeks, executing a MethodSCRIPT while powered from a battery, and saving data to onboard storage. Manually control the Sensit Wearable via Bluetooth or USB using the Android app PStouch, or using our PC software PSTrace
