The rapid growth of the electronics industry has brought about significant environmental challenges, including electronic waste and carbon emissions. To reduce the environmental impact, innovative sensing technologies are being explored. Laser-induced graphene (LIG) has emerged as a promising sensor fabrication technology, due to its unique properties and energy-efficient manufacturing process. This work focuses on developing a humidity sensor using wood and LIG under ambient laboratory conditions, aiming for a fully biodegradable sensor. An interdigital electrode design was chosen to implement the sensor and tested over a wide range of relative humidity values.
