A novel method to transfer porous PDMS membranes for high throughput Organ-on-Chip and Lab-on-Chip assembly

We present a novel method to easily and reliably transfer highly porous, large area, thin microfabricated Polydimethylsiloxane (PDMS) porous membranes on Lab-on-Chip (LOC) and Organ-on-Chip (OOC) devices. The use of silicon as carrier substrate and a water-soluble sacrificial layer allows a simple and reproducible transfer of the membranes to...

Microfabricated tuneable and transferable porous PDMS membranes for Organs-on-Chips

We present a novel and highly reproducible process to fabricate transferable porous PDMS membranes for PDMS-based Organs-on-Chips (OOCs) using microelectromechanical systems (MEMS) fabrication technologies. Porous PDMS membranes with pore sizes down to 2.0 μm in diameter and a wide porosity range (2–65%) can be fabricated. To overcome issues...

Shade estimation over streams using distributed temperature sensing

The characterization of temporal and spatial distribution of sunlight is essential for understanding energy transport in natural ecosystems. Fiber?optic distributed temperature sensing (DTS) allows meter resolution measurements of temperature at subminute resolution. The difference in temperature due to absorption and reflection of a pair of...

Persuasion for a Healthier Life: Persuasive Technology Design Guidelines from the Precious Project for Indian diabetics

Health behaviour change is a key issue in India and especially for reducing diabetes related risks. But the issue is confined neither to diabetes nor to India. After the proliferation of personal digital devices and widespread internet access, persuasion for behaviour change has taken new forms. In this paper we propose 8 design guidelines for...
