The filler material is a plant-based cellulose material. The one or more portions define interstices. A containing structure contains the matrix. A consumable substance is infused within the filler material. The consumable substance is nicotine, a flavorant, a pre-aerosol formulation, a combination thereof, or a sub-combination thereof. The device includes a heating section with the capsule. ## Claims ### Claim 1 A device, comprising: a heating section including, a first housing, a heating element in the first housing, and a capsule within heating proximity of the heating element, the capsule including, a matrix including, shredded strands of a filler material that is water-insoluble, the filler material including a plant-based cellulose material, the plant-based cellulose material including more than 98% alpha-cellulose material, 0.01% to less than 2% ash and a remainder is hemicellulose, the alpha-cellulose being one of a tobacco cellulose or both a non-tobacco plant based cellulose and the tobacco cellulose, the shredded strands defining interstices, a containing structure containing the matrix, and at least one first substance infused within the filler material, the at least one first substance being one of nicotine, at least one first flavorant, a pre-aerosol formulation, a combination thereof, or a sub-combination thereof, and the first housing defining an air inlet and an air outlet that are configured to establish an airflow path that passes across, passes through or both passes across and passes through the capsule. ### Claim 2 (depends on 1) The device of claim 1, further comprising: a power source; at least one first sensor; and control circuitry in electrical communication with the at least one first sensor and the power source, and the control circuitry being configured to cause the power source to send an electrical current to the heating element. ### Claim 3 (depends on 2) The device of claim 2, wherein the at least one first sensor is configured to detect at least one first parameter, the at least one first parameter being at least one of a resistance of the heating element, a temperature of the heating element, a temperature of the matrix of the capsule, a temperature of the capsule, a draw of air, a sub-combination thereof, or a combination thereof. ### Claim 4 (depends on 3) The device of claim 3, wherein the control circuitry is configured to cause the power source to send the electrical current to the heating element based on the at least one first parameter. ### Claim 5 (depends on 4) The device of claim 4, wherein the electrical current is variable based on the at least one first parameter. ### Claim 6 (depends on 1) The device of claim 1, wherein the capsule further includes, a flow restriction section with a first end and a second end, the first end of the flow restriction section being connected to the matrix; and a filter connected to the second end of the flow restriction section, the filter being devoid of a consumable substance. ### Claim 7 (depends on 6) The device of claim 6, wherein, the containing structure contacts at least a side surface of the flow restriction section and at least a side surface of the filter to contain the matrix, the flow restriction section and the filter together, and the flow restriction section defines an internal void space with a flow restrictor in the internal void space, the flow restrictor being spaced apart from one of the first end, the second end, or both the first end and the second end. ### Claim 8 (depends on 6) The device of claim 6, wherein, the flow restriction section defines an internal void space with a flow restrictor in the internal void space, the flow restrictor being spaced apart from one of the first end, the second end, or both the first end and the second end. ### Claim 9 (depends on 1) The device of claim 1, wherein the at least one first substance includes nicotine, a weight of the nicotine being between about 1 mg and 15 mg. ### Claim 10 (depends on 1) The device of claim 1, wherein the at least one first substance includes the at least one first flavorant, the at least one first flavorant being a tobacco extract. ### Claim 11 (depends on 1) The device of claim 1, wherein the at least one first substance includes the at least one first flavorant, the at least one first flavorant being a non-tobacco flavorant. ### Claim 12 (depends on 1) The device of claim 1, wherein the at least one first substance includes the at least one first flavorant, the at least one first flavorant being a tobacco extract. ### Claim 13 (depends on 1) The device of claim 1, wherein the at least one first substance includes the at least one first flavorant, the at least one first flavorant being a non-tobacco flavorant. ### Claim 14 (depends on 1) The device of claim 1, wherein the capsule further includes a filter. ### Claim 15 (depends on 1) The device of claim 1, wherein the capsule further includes: a flow restriction section with a first end and a second end, the first end of the flow restriction section being connected to the matrix. ### Claim 16 (depends on 15) The device of claim 15, wherein the capsule further includes: a filter connected to the second end of the flow restriction section, the filter being devoid of a consumable substance. ### Claim 17 (depends on 16) The device of claim 16, wherein the containing structure contacts at least a side surface of the flow restriction section and at least a side surface of the filter to contain the matrix, the flow restriction section and the filter together. ### Claim 18 (depends on 15) The device of claim 15, wherein the flow restriction section defines an internal void space with a flow restrictor in the internal void space, the flow restrictor being spaced apart from one of the first end, the second end, or both the first end and the second end. ### Claim 19 (depends on 1) The device of claim 1, wherein the containing structure is at least one of a mesh, cellulose, plant-based cellulose, fabric, cotton, fibers, threads, textiles, paper, tipping paper, a same material as the filler material, a sub-combination thereof, or a combination thereof. ### Claim 20 (depends on 1) The device of claim 1, wherein the containing structure includes the filler material. ### Claim 21 (depends on 1) The device of claim 1, wherein the shredded strands have a first thickness in a range of about 1 mm to 3 mm. ### Claim 22 (depends on 1) The device of claim 1, wherein the capsule further includes, a filter connected to an end of a flow restriction section, the filter being devoid of a consumable substance.
