In October 2021, for the second year running, the U.S. Postal Service implemented a temporary price increase due to the heightened number of online shopping packages being delivered in the run up to the holidays. No surprise, as ever-expanding e-retail dreadnaughts like Amazon are setting us up for another Christmas filled with home deliveries. It’s perfect timing then that the smart doorbell has skyrocketed in popularity.
Effective decontamination and sterilization of hospital wards and bathrooms is essential in reducing the risk of cross infection. This is especially important during the COVID-19 pandemic, when we consider that there are just 20 critical care beds per 100,000 people in the US. Here, we explore the vital role robotics play in sterilization and what to consider when choosing a power supply.
Robots for military, medical, surveillance and logistics purposes are all assisting humans by undertaking dangerous or monotonous tasks but can still have very different power needs, based on the legislations they are subject to and their reliance on battery power. Here we examine the vital functionalities of bomb disposal robots, drones, surgical robotics and logistics robots that can influence the power solutions they require.
For large medical devices, battery power is mainly used as a backup in case of mains failure. For handheld and wearable devices however, they are the primary power supply. Any downtime could threaten the well-being of the patient, which makes the efficacy of the batteries just as vital as the monitors or sensors they might be powering.
For over 130 years, engineers have sought to assist those who struggle with walking through the use of wearable mobile machines called exoskeletons. Many and varied power sources have been trialled for these machines over time, from compressed gas bags to steam power. So, what led to batteries being selected as the modern-day power source of choice and will they still be relied upon in the future?
Measurement is a fundamental requirement of scientific and engineering disciplines. Without precise measurements as a basis, all future work is doomed to inaccuracy or ineffectuality. As such, it’s vital that test and instrumentation equipment can be relied on to provide consistent, accurate measurements. Here, we explore the role batteries play in achieving reliable instrumentation — and the challenges design engineers should consider.
Ultralife has taken steps towards enhancing its battery portfolio for the renewable energy sector – with the addition of the URB0023 stackable battery and by approving SuperWind Turbines for use with it and other Lithium Iron Phosphate (LiFePO4) batteries.
Closed circuit television (CCTV) has been a feature of our world for almost a century now. First conceived in 1927 by gifted Russian inventor Léon Theremin, it is estimated there are over six million cameras in the UK alone — one for every eleven citizens. The need for video surveillance for safety and security is clear, but what are you supposed to do when mains power is unavailable?
The global home security systems market size is expected to reach $78.9 billion by 2025, with smart security systems becoming increasingly prevalent in people’s homes to protect against intruders, monitor entrances and detect floods. With sensors now dotted around the home, the power requirements of smart security devices have changed from traditional alarm systems.
Scientists require accuracy in their measurements, which is why – in early 2019 – the definition of a kilogram was modernised.
As measurements become more precise; demands for accuracy are also placed on the equipment that calculates, interrogates, monitors or communicates them; which is where selecting the optimum battery can prove invaluable.
