Motivated by the demands of the integrated power system in the modern wearable electronics, this paper presents a new method of inductor-less switched-capacitor (SC) based DC-DC converter designed to produce two simultaneous boost and buck outputs by using a 4-phases logic switch mode regulation. While the existing SC converters missing their reconfigurability during needed spontaneous multi-outputs at the load ends, this work overcomes this limitation by being able to reconfigure higher gain mode at dual outputs. From an input voltage of 2.5 V, the proposed converter achieves step-up and step-down voltage conversions of 3.74 V and 1.233 V for Normal mode, and 4.872 V and 2.48 V for High mode, with the ripple variation of 20-60 mV. The proposed converter has been designed in a standard 0.35 µm CMOS technology and with conversion efficiencies up to 97-98% is in agreement with state-of-the-art SC converter designs. It produces the maximum load currents of 0.18 mA and 0.36 mA for Normal and High modes respectively. Due to the flexible gain accessibility and fast response time with only two clock cycles required for steady state outputs, this converter can be applicable for multi-function wearable devices, comprised of various integrated electronic modules.

Today's engineering industries require graduates with a broad range of soft skills, which include teamwork, communication and integrity. Therefore, more accreditation bodies now recommend team-learning activities to be embedded in their engineering programmes. However, hardworking students often find group projects demotivating, especially if their contributions are not accurately reflected in their individual grades. To address these issues, we demonstrate that Electronic Laboratory Notebooks can be used to promote student collaboration and teamwork on a group project. They can also help instructors assess student contributions fairly. During our investigations, we noticed that students have used Electronic Laboratory Notebooks as social interaction tools that enable text, data, images and recorded audio to be exchanged. Consequently, the aim of this manuscript is to describe the experiences of 58 transnational undergraduate students in using six different software products for a team-based learning activity. According to our investigations, Electronic Laboratory Notebooks had a positive impact on supporting Team Based Learning in a new electronic engineering course. The outcomes of our investigations can help create effective teaching and learning resources for undergraduate students in Electronic Engineering. They can also help engineering faculty make informed decisions regarding the introduction of Electronic Laboratory Notebooks in undergraduate research activities.

A 4channel 12-bit high-voltage radiation-hardened digital-to-analog converter for low orbit satellite applications.

Smart electronic contact lenses typically integrate communications modules, electronic circuitry, sensors and an energy storage reservoir. These smart contact lenses can be used in medical applications that include monitoring patient glucose and intraocular pressure (IOP). However, due to the health hazards associated with chemical batteries, as well as the inconvenience of consistently charging the energy storage reservoir, a sustainable and reliable energy harvesting system is required. Therefore, the aim of this research is to design and develop an optimised harvester for a contact lens application. In fact, this paper introduces a novel hybrid microenergy harvester concept, which aims to produce sufficient electricity to power an electronic contact lens using light and electromagnetic radiation that are scavenged from photovoltaic cells and radio frequency technology.
