Low-cost, interdigitated capacitive sensor using laser-written graphene foam for touch, proximity, and liquid level detection

Flexible capacitive sensors are gaining popularity in place of sophisticated optical sensing or bulky mechanical designs for specific applications such as proximity/gesture detection and liquid level sensing. So, here, we propose Laser Induced Graphene Foam (LIGF) based planar capacitive sensors, wh...
