Wood Carbon Sponge Could Be Future of Wearable Sensors

Engineers have for the first time demonstrated that wood can be directly converted into a carbon sponge capable of withstanding repeated compression and other extreme mechanical conditions. The new sponge can be used in various applications including electronic devices and sensors. The wood carbon sponge overcomes several limiting factors of other lightweight, compressible carbon sponges because it is simpler, less expensive, and more sustainable to produce.
