Collecting data from smartphones can provide useful information for health research, but developing mobile health (mHealth) apps requires extensive resources and implies often overlooked regulatory and privacy-related requirements. Mobile health "aggregators" like HealthKit or Google Fit and specialised platforms may allow reducing costs in mHealth research. Current platforms, however, do not efficiently exploit mHealth aggregators and provide little attention to regulations. We propose an open-source platform that can be used by health researchers without the need to develop custom apps. The platform has a strong focus on regulatory compliance, patient consent and transparency, and allows collecting data through electronic surveys and querying aggregators. We tested the feasibility of our platform in a pilot study with 18 healthy volunteers. The results show that the participants' app is usable and well-accepted and is able to frequently collect data about physical activity from both phones and connected wearables. Some limitations were identified regarding data loss because of insufficient connectivity and the impossibility of extracting data from wearables that are not compatible with aggregators.

The concept of utilizing the Coandia effect to produce stable flight in saucer type Aerial Vehicles (AV) was first conceived in 1935 by Henri Marie Coanda. Coanda's proposed AV design remained a relatively unexplored curiosity for decades until the recent surge in popularity of small Unmanned Aerial Vehicles (UAV) revitalized interest in the topic. Coandä effect UAV offer some distinct advantages over standard multirotors due to their robust frame design, which offers a unique mix of crash resistance, flight safety, and flight performance making them ideal for Human-Robot Interaction (HRI) applications. While much work has been performed in the area of characterization for Coanda surfaces and improved mechanical design of saucer type UAV, little work has been found in the literature discussing stability and attitude control of the platform. This work seeks to contribute to the study of these drones by introducing an approximate servo mapping for desired control effort of a particular prototype, and an experimental control law implemented within the framework of a modified commercially available flight stack.

As cancer becomes the No.1 cause of the death in Japan, endoscopic surgery is gaining attentions. In this paper, endoscopical tool to grip and lift the targeted tumor in ESD (endoscopic submucosal dissection) surgery is proposed. This articulated microarm is part of new ESD surgery concept in which two wire-driven microarms (1 times 1 times 25 mm) from the tip of the endoscope help lift the tumor to cut. This research needs to emphasize a new fabrication method of arm which is fabricated by photolithography and electroplating. The microarm is composed of five layers. Individual layers are fabricated separately and assembled together in the end. The microarm uses the elastic deformation of metal to bend (Cu or Phosphor Bronze). It is feedback control with PID using a strain gauge attached to the articulated joint. This technique enabled the further miniaturization of the microarm, but it also comes with a downside. It is difficult to build a 3-dimensional structure. We overcame this problem by proposing an assembly method (STAMP: stacked microassembly process). Electroplated layers are assembled by stacking up on top of each other. This assembly process is feasible to produce multiple microarms at one assembly, thus mass-production with low cost is possible. A strain gauge is attached to the elastic joint as an angle sensor.
