NEPTUNE series self-sensing/water-activated batteries are standard dry thin-film batteries that take advantage of sweat or other naturally occurring moisture as the activation stimuli. 

The system can be employed for sweat sensing, moisture detection, flood protection, and environmental sensing applications. The display and output can be tailored towards specific requirements based on customer requests. 

WATER ACTIVATED: Switched on with minimal amount of water-based liquid

FLEXIBLE: Bending radius up to 60°, consistent output under bending

ULTRA-THIN: < 1.0 mm

SAFE: No toxic and harmful substances, leak-proof design

STABLE: Temperature Range between -20°C to 60°C
