- Creating personalized 3D printing objects has become increasingly popular with the advance in end-user modeling tools and fabrication techniques. However, it remains challenging for novice makers to design and fabricate functional objects with mechanical motion such as linear or rotational. To empower users to add mechanical movements to their models for particular needs, we first investigate the commonly used 3D printable mechanisms and parameterize four mechanical primitives. We then provide a computational approach to reconfigure the mechanical primitives to user-provided 3D models, with an underlying structural optimization procedure according to a specified bending force. We further showcase a set of design examples and conduct a user study to demonstrate the potential of our approach in creating personalized functional artifacts.

SME creation facilitation process at Universities
- 2012
-
Ingår i: [Host publication title missing].

Konferensbidrag (refereegranskat)abstract
- Much research on SMEs is aimed at researching SMEs after the fact that they have become SMEs. However all SMEs as well as larger companies start as an idea in the head or heads of one or many persons - the prospective entrepreneurs. The purpose of this paper is to investigate how SMEs can be created by transforming ideas into real companies. More specifically we will investigate if and how Universities can facilitate this process by running international cross-functional courses. Our hypothesis is that in order to create a SME three topics are of pivotal importance: • Specialist Competence in the business area • General management competence • Financial capital During the fall of 2012 we will test the hypothesis by running a university course called international Marked Driven Engineering (iMDE) in cooperation between Lund University and Zhejiang University. Technology faculties from both Universities are involved – students as well as teachers. Their participation is crucial to cover specialist competence in the business area – technology-based enterprises. Management faculties from both Universities are involved – students as well as teachers. Their participation is crucial to cover general management competence in setting up, funding and running an enterprise. When it comes to financial capital our hypothesis is that for clever business ideas, financial capital can be raised in order to industrialize such a business idea. In the first trial run 8 business ideas will be generated and tested in the Hangzhou area during the period 120910-121019. Each of the 8 teams will consist of 8 persons – blended to cross-fertilize engineering-business, Chinese-Swedish and male-female participants. With the support of university teachers with the same blend the aim is to create embryos of SME’s.

Synthesis and high pressure induced amorphization of C60 nanosheets

- C-60 nanosheets with thicknesses in the nanometer range were synthesized by a simple method. Compared to bulk C-60, the lattice of the nanosheets is expanded by about 0.4%. In situ Raman spectroscopy and energy-dispersive x-ray diffraction under high pressures have been employed to study the structure of the nanosheets. The studies indicate that the bulk modulus of the C-60 nanosheets is significantly larger than that of bulk C-60. The C-60 cages in nanosheets can persist at pressures over 30 GPa, 3 GPa higher than for bulk C-60. These results suggest that C-60 crystals in even small size will be a potential candidate of superhard materials.

AnimSkin : Fabricating Epidermis with Interactive, Functional and Aesthetic Color Animation
- 2017

Konferensbidrag (refereegranskat)abstract
- Human epidermis, as the largest organ on body, has become a new design platform for wearable computing. The availability of miniature electronics makes more possibilities for on-skin designs. In this paper, we present AnimSkin, a thin-film interface, which will emit dynamic color animations directly on skin. This is done by using thermochromic material embedded with transparent electrode acting as a capacitive sensor. Moreover, an accessible and low-cost fabrication method is introduced. Individuals could also customize aesthetic graphic designs by following the detailed fabrication process to achieve personalized patterns. We propose four different dynamic types of color animation by applying certain voltage to the heating circuitry. With two examples, Email Reminder and Light Control System, we demonstrate how AnimSkin can be integrated into everyday life, and specifically, we show how AnimSkin can benefit areas such as on-skin design, thin-film interface and beauty technology.

Crafting Concrete as a Material for Enhancing Meaningful Interactions
- 2017

- Concrete is a composite material mostly used for the buildings and road surfaces ever since early human history, and which also can be used in contemporary product design as its unique aesthetic properties. In this paper, we present a series of small-scale explorations of concrete crafted as a central material, first utilizing its hygroscopicity interacting as an ephemeral and dynamic display; and secondly eliciting tactile interaction for its unique surface textures. Through hands-on engagement to unveil concrete potential when fabricated with digital technologies, we discuss how this large-scale and ubiquitous material could bring particular and intriguing experiences in our everyday lives, most importantly how can the potential of concrete be framed and described and enhance meaningful concrete reflections within HCI community.
