“…This device harvests energy from ambient light using photovoltaic cells at the back of an e-ink display and updates over Bluetooth when enough energy is harvested. A more elaborate sensing and data transmission scheme has been described by Cowell et al [6]. They show how indoor light energy can be harvested to trickle charge a high-power energy reservoir and also meet the power demand of a wireless sensor network with voltage-triggered sensing and data transmission.…”

The interactive, digital future with its seductive vision of Internet-of-Things connected sensors, actuators and displays comes at a high cost in terms of both energy demands and the clutter it brings to the physical world. But what if such devices were made of materials that enabled them to self-power their interactive features? And, what if those materials were directly used to build aesthetically pleasing environments and objects that met practical physical needs as well as digital ones? In this paper we introduce PV-Tiles-a novel material that closely couples photovoltaic energy harvesting and light sensing materials with digital interface components. We consider potential contexts, use-cases and light gestures surfaced through co-creation workshops; and, present initial technological designs and prototypes. The work opens a new set of opportunities and collaborations between HCI and material science, stimulating technical and design pointers to accommodate and exploit the material's properties.
