document: 2.	Power supply:
  The need exists for a safe and stable power supply for a series of operations, including image collection, data processing, data transmission, and sample testing.
  3.	Environmental stability:
  Many POC platforms depend on biomolecules and chemicals with temperature-sensitive characteristics, and thus, improvements in storage stability and continuous temperature monitoring in resource-lacking conditions are essential for reducing possible test failures. 
  4.	Commercialised ability:
