Wearable Sensors Fabricated by 3D‐Printed Composite Hydrogel with 2D Fillers

open access: yesSmall Methods, EarlyView.
This review explores how 3D printing integrates 2D conductive fillers into hydrogel matrices to fabricate high‐performance flexible sensors. By tailoring microstructures and nanomaterial interactions, these devices achieve enhanced sensitivity, durability, and environmental adaptability for healthcare monitoring, human‐machine interfaces, and robotic ...

Costs of Producing Biogas at Dairy Farms in The Netherlands [PDF]

open access: yes
By 2020, Dutch dairy chains envisage to be self‐sufficient with regard to energy used by dairy farms and dairy processors. This would require dairy farms to produce 25 PJ per year, possibly by a combination of wind, solar and biogas.

Innovation in the Spaces In‐Between: Creating the Nexus Between Human and Non‐Human Actors in Systemic Innovations

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT By combining theories of system thinking with a post‐humanist approach, we established a nexus between human and non‐human systems in the examination of systemic innovation. By doing so, we shed light on the interdependencies that exist between human and non‐human systems and contribute theoretically as well as methodologically to theories on ...

Organic farming without fossil fuels - life cycle assessment of two Swedish cases [PDF]

open access: yes, 2013
Organic agriculture is dependent on fossil fuels, just like conventional agriculture, but this can be reduced by the use of on-farm biomass resources. The energy efficiency and environmental impacts of different alternatives can be assessed by life cycle

Systemic Governance From Below: Story Telling to Empower Access to the Commons Through Mapping and Modelling: A Mixed Methods Approach

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Access to forests, farming land and the Citarum river is limited in Tarumajaya; furthermore, many do not own their own housing and are dependent on the public and private landowners in the area. The region of Tarumajaya faces significant challenges in access to crucial resources such as forests, farming land and the Citarum river, leading to a
