With that, the device has been fully disassembled!

In terms of repairability, most of the components can be replaced if available from the manufacturer. Apart from the screws, the battery and the DST, all components seem custom made for this device.

The device uses 4 standard screws which could be replaced by procuring them online or hardware stores.

The battery can be replaced, but it would require a soldering iron to connect to the board.

The device also uses a proprietary software and a black-box algorithm which provides the analysed data. That cannot be re-engineered easily.
