Figure 1. Despite being known for entertainment, Disney has also gained an edge in technological research via 3D printing and modeling. Shown here is one of the compliant mechanisms created in a study from Disney’s research division.

New Disney Study Suggests More Effective 3D Printing Designs

By Caleb Sooknanan ’20 Compliant mechanisms are mechanisms that can transfer forces or displacements to other points along their bodies. 3D printing can be used to quickly and effectively design compliant mechanisms for commercial use, but more work is needed to understand how such devices can be printed. Doctor Bernhard Thomaszewski and researchers from Disney Research Zurich in Switzerland devised a computational tool that would … Continue reading New Disney Study Suggests More Effective 3D Printing Designs

Figure 1. Scientists strive to create wearable smart devices that can detect physiological phenomena in real time. According to a study from UC Berkeley, new ear devices can be 3D printed and used to indicate patients’ true body temperatures.

3D-Printed Ear Devices Detect Core Body Temperature

By Caleb Sooknanan ’20 Healthcare sensors are frequently used to detect skin temperature, but more research is needed to design a device that can pinpoint core body temperature levels and help doctors predict the likelihood of fever, fatigue, and other physiological phenomena. Professor Ali Javey and researchers at the University of California, Berkeley designed a printable smart device that — when placed on a patient’s … Continue reading 3D-Printed Ear Devices Detect Core Body Temperature

Figure 1: Stairs are frequently a major obstacle for individuals with neuromuscular conditions.

Researchers Develop Low-Power Assistive Stairs

By Anna Tarasova ’19 Many elderly and mobility-impaired individuals are unable or tend to be unwilling to use stairs. While assistive technologies exist, they are frequently costly and unsustainable. The principle of energy recycling has been previously applied to walking assistance mechanisms that take advantage of the continuous braking and propelling of the legs. However, during stair-walking, ascent is a period of constant propulsion and … Continue reading Researchers Develop Low-Power Assistive Stairs

Capsule Robots Can Be Used for Biosensor Implantation

By Caleb Sooknanan ’20 Biosensors have become increasingly practical within the medical field, as they can detect different biometrics such as heart rate and body temperature levels. However, current biosensors can wear out quickly and elicit health problems such as trauma. Many efforts — especially in the area of capsule robotics — have been made to develop biosensors that are noninvasive and effective at monitoring … Continue reading Capsule Robots Can Be Used for Biosensor Implantation

Figure 1: Researchers at the Yokohama City University Graduate School of Medicine in Japan used computational fluid dynamics (shown) to analyze the flow distribution of anticancer agent into the branches of the external carotid artery during intra-arterial chemotherapy.

Computational Fluid Dynamics Can Be Used to Treat Oral Cancer

by Caleb Sooknanan ’20 Surgical procedures have often been used to treat oral cancer. However, these procedures can cause oral dysfunction — often in the form of speech and breathing difficulties — and thereby harm respiratory organs. To preserve organ function, intra-arterial chemotherapy (IAC) has become a valuable form of treatment. IAC releases more anticancer agents into tumor-feeding arteries than intravenous systemic chemotherapy. However, anticancer … Continue reading Computational Fluid Dynamics Can Be Used to Treat Oral Cancer

The Importance of Synthetic Core Promoters in Yeast Fine-Tuning Expression

    By Caleb Sooknanan ‘20 In genetic engineering, metabolic pathways and genetic circuits can be manipulated in microbes to produce chemicals or activate certain functions. To do this, gene expression must be fine-tuned to balance and optimize protein levels of metabolic enzymes or regulators.  Manipulating these in unicellular eukaryotes often involves core promoter sequences, the minimal portion of the promoter required to initiate DNA … Continue reading The Importance of Synthetic Core Promoters in Yeast Fine-Tuning Expression

Photocurable Bioinks and 3D-Printed Hydrophilic Drugs

  By Caleb Sooknanan ’20 Pharmaceutical dosages are often defined as the amount of active pharmaceutical ingredient (API) that has a therapeutic effect in the most patients. Using such a generalized method does not account for variations in patient genomic and pathophysiological status, leading to potential negative side-effects. Personalized medicine intends to provide patients with more individualized API concentrations in their prescriptions. However, changes in … Continue reading Photocurable Bioinks and 3D-Printed Hydrophilic Drugs

Harvesting Energy with Magnetic Springs

      Michael D’Agati ‘18 Developing better ways to power portable electronic or wireless sensor systems has become more desirable in our increasingly mobile world. Multiple projects have proposed harvesting mechanical stresses from the human body to power these devices, but many of them use piezoelectric materials, which create current in a circuit due to changes in pressures on the material. Many small piezoelectric … Continue reading Harvesting Energy with Magnetic Springs

Creating Electricity Using the Motion of the Body

    Michael D’Agati ‘18 Wearable electronics, such as the Fitbit and Apple Watch, have started to flood the consumer marketplace. Flexible energy sources, rather than traditional batteries, are garnering more popularity to power this wearable technology because energy created by a moving human body – an unlimited power source – can be harvested and used to power them. A team of researchers led by … Continue reading Creating Electricity Using the Motion of the Body

Sensing Human Touch with Low Frequencies

Michael D’Agati ‘18 Passive touch sensing flexible keyboards could supplement low power displays. Sensing Human Touch with Low Frequencies. From touch screens to keypads, the technology that senses a human touch is vital to communication in the 21st century. This technology found in the displays of smartphones and tablets requires active touch sensing technologies. In other words, the display requires power delivered via battery or … Continue reading Sensing Human Touch with Low Frequencies
