Environmental considerations for soft electronics systems and energy sources request for proposals


The development of new soft materials may help make sophisticated and comfortable consumer devices ubiquitous in our daily lives. While dramatically improving many facets of life, the proliferation of ubiquitous volumes of consumer electronics poses ethical and societal challenges, namely in the generation and accumulation of electronic waste (e-waste) and the dependence on rare minerals for the manufacture and powering these devices. Currently, the power requirements of portable consumer electronics devices is limited by commercial solutions in a narrow set of battery material systems. These limitations rely on materials that are either inherently unsafe or material sets that face future scarcity issues if reclaim technologies do not scale with proliferation. Neither outcome is desirable to consumers. Additional challenges result from the materials and manufacturing processes of electronics in general that require the sourcing of materials that have large environmental and societal impacts both during extraction and end-of-life disposal. To anticipate and mitigate the challenges related to energy storage and harvesting for consumer electronics as well as general mitigation of e-waste, technology developers must look for system-level solutions now.

To foster further innovation in this area, and to deepen our collaboration with academia, Facebook is pleased to invite faculty to respond to this call to consider and address the ethical environmental impacts of consumer electronics energy systems and e-waste reclaim. We anticipate issuing up to a total of 20 awards, each in the 100k to 150k USD range. Payment will be made to the proposer’s host university as an unrestricted gift.

Areas of Interest

Areas of interest for this RFP include evaluation of the ethical and environmental considerations of the development and decomposition of soft material technology. The proposals should focus on materials that could integrate into a consumer electronics device, and teams should consider systems that could fit around the forearm or wrist.

Teams do not need to optimize for the energy density of the battery, but should instead focus on frameworks and processes that promote ethical end-to-end technology development and use.

Materials and systems that are in scope for this RFP include the following:

  • Soft elastomeric energy systems, including storage and harvest
  • Batteries
  • Super capacitors
  • Environmental energy harvesting (e.g. thermal -> electrical, kinetic -> electrical)
  • Biodegradable, but performant, alternatives to standard flexible circuit materials (e.g. polyimide)

Materials and systems that are not in scope for this RFP:

  • Very small quantities of novel materials (e.g. producing very small quantities of a material that are not scalable)

Areas of interest include, but are not limited to, the following:

1. Ethically-robust framework for evaluating system decomposition

Proposals for this topic should focus on (1) defining an ethical framework for evaluating life-cycle analysis (LCA) processes for soft energy materials, and (2) developing and implementing a life-cycle analysis that is in line with this framework. The framework should capture the identification of any byproducts that may result from decomposition processes.

Proposals should include the following activities:

  • Defining an ethical framework for evaluating a life-cycle analysis process for soft energy materials.
  • Performing a life-cycle analysis and evaluating the effectiveness of the analysis for quantifying material system decomposition.
  • Quantifying the life-span and stability of the material.
  • Assessing the life-cycle analysis according to the ethical framework, and identify any ethical consideration gaps. Is there an ethical environmental consideration that is not being captured through this LCA method?
  • Demonstrating how the ethical framework can generalize to multiple soft materials.

2. Environmentally-friendly accelerated decomposition of soft or flexible battery materials

Proposals for this topic should focus on demonstrating and quantifying the environmental impact of accelerated decomposition for battery materials. The accelerated decomposition method of choice can be an established method, now applied to soft elastomers or flexible composites for consumer electronics technology, or a completely new method.

Proposals should include the following activities:

  • Establishing biodegradable electrolytes that are more environmentally friendly than lithium. Consider answering: what ethical framework would capture this advantage? Can you apply this framework to different battery technologies?
  • Demonstrating low energy methods that accelerate the decomposition of a soft or flexible energy material. Identify the stimuli that accelerate the decomposition
  • Quantifying the holistic environmental impact of the method, including the environmental impact of any byproducts of the decomposition processes.
  • Describing the choice of soft or flexible material, including a description of its usefulness for soft or flexible consumer technology.

3. Environmentally-friendly soft or flexible energy generating systems

Proposals for this topic should focus on the identification of environmentally-friendly, soft or flexible energy-generating systems. Proposals should also include a benchtop demonstration of how these materials could apply to small packages (equivalent in size to consumer electronics: smart phones, tablets, etc). The energy generator system can be an established environmentally-friendly material, now applied to soft or flexible for consumer technology, or a completely new material.

Proposals must include the following activities:

  • Developing benchtop demonstrations of significant (greater than 1 mW/cm2) electric power generation. Ideally the demos will have surface areas far less than one m2.
  • Demonstrating methods of benign manufacture or decomposition for extant high efficiency energy harvesting transducers. Typically existing energy harvesters use materials (II-VI, III-V, Si, etc) that may require toxic processes or byproducts to produce or recycle — how can we mitigate or eliminate these negative environmental impacts at the point of device manufacture or decomposition?
  • Demonstrating manufacturing methods of energy generator transducers from biodegradable or bio-derived/decomposable materials.
  • Development of an ethical framework that could be used to assess the environmental impact of the chosen material.


Proposals should include:

  • A summary of the project (1-2 pages) explaining the area of focus, a description of techniques, ethical frameworks, any relevant prior work, and a timeline with milestones and expected outcomes.
  • A draft budget description (1 page) including an approximate cost of the award and explanation of how funds would be spent
  • Curriculum Vitae for all project participants.
  • Organization details; this will include tax information and administrative contact details


  • Awards must comply with applicable US and international laws, regulations and policies.*
  • Applicants must be current full-time faculty at an accredited academic institution that awards research degrees to PhD students.
  • Applicants must be the Principal Investigator on any resulting award.
  • Applicants may submit one proposal per solicitation.
  • Organizations must be a nonprofit or non-governmental organization with recognized legal status in their respective country (equal to 501(c)(3) status under the United States Internal Revenue Code).
