Shipping damage, measured in real time: How wireless origami cushioning could improve logistics

Origami, the traditional Japanese art of paper folding, has received considerable attention in engineering. By applying paper-folding principles, researchers have created compact structures that are flexible, lightweight, and reconfigurable across aerospace, medicine, and robotics.

Self-aware biosensors boost digital health monitoring

Smart biomedical devices are transforming modern health care, using skin-mounted sensors to capture in-depth health information directly from the body. As clinicians increasingly use biosensing devices to guide patient care, accurate and reliable signal acquisition is critical. A team at KAUST has developed a new system that can rapidly detect when the electrodes of devices such as heart monitors start to detach from the skin.

I've been super busy with real world stuff but finally got to tick off a job by adding a SHT30 Temp and Humidity Sensor to my little setup in the cold frame I built last year.

It means that it's now reporting temp, humidity and battery voltage which actually starts being useful. We've had very variable weather in the last few weeks, jumping from hot days to near freezing so it's helpful to know how the cold frame is functioning. ITs all powered by some flexible solar panels

I've set it up on my #grafana dashboard of course...

RuView project leverages ESP32 nodes for WiFi-based presence detection, pose estimation, and breathing/heart rate monitoring

RuView project leverages ESP32 nodes for WiFi-based presence detection, pose estimation, and breathing/heart rate monitoring

RuView is an open-source "WiFi DensePose" implementation leveraging multiple ESP32 nodes to turn WiFi signals into real-time human pose estimation, vital sign monitoring, and presence detection without relying on video cameras. WiFi DensePose is a sensing technique, first explored in academic research, that leverages WiFi signals to reconstruct human pose. RuView implements this technique in Rust or Python, and relies on your WiFi router and several ESP32 nodes to track body pose, detect breathing rate, and measure heart rate even through walls. As we'll discuss below, this project has its own controversy, as some claim it's fake. The solution relies on Channel State Information (CSI) disturbances caused by human movement to reconstruct body position, breathing rate, heart rate, and presence in real time using "physics-based signal processing and machine learning". That obviously means you need CSI-capable hardware, and not all consumer WiFi nodes implement it. The project description lists various

RainbowLink-V2 compact USB-to-serial converter features 12V output, dual TTL, isolated RS-485 and RS-232 interfaces

DFRobot's RainbowLink-V2 USB-to-serial converter features four independent channels, namely one isolated RS-485, one isolated RS-232, and two TTL interfaces usable simultaneously. The compact tool also converts 5V provided from the host's USB interface to 12V/800mA, 5V/2A, and 3.3V/200mA outputs, eliminating the need for a separate power adapter. RainbowLink-V2 (TEL0190) specifications: USB - 1x USB Type-C port for power and adata Serial 2x TTL (3.3V) via headers 1x fully isolated RS485 channel via lever terminal 1x fully isolated RS232 channel via lever terminal Baud Rate - 2400 to 128000 bps Misc 3x Power LEDs for 3.3V, 5V, and 12V 4x Link LEDs for TTL 1/2, RS232, and RS485 12AWG - 22AWG wires supported on lever-type spring terminals Built-in short-circuit protection and overcurrent protection (but users are still recommended to avoid short-circuiting to prevent damage) Input voltage - 5V via USB-C port Output voltage 3.3V up to 200mA via header 5V up

Optical sensors struggle with clear objects on the line because light just passes through them.

We compared the two best alternatives: Capacitive vs. Ultrasonic sensors. Our guide covers sensing ranges, immunity, and use cases (bottle counting vs. micro-plastics).

Why city street surveys miss methane leaks, and what that means for safety

The complexities of urban environments—like variable winds off tall buildings or surfaces—significantly impair the ability to detect natural gas leaks from underground pipelines, a new study shows. SMU researchers found that detection probability can be reduced by 16 percentage points for methane gas leaks from main pipelines and by as much as 38 percentage points for service line leaks in urban areas, compared to rural settings.
