Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy.

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Wireless microcontroller TI CC1310F128RGZT 04.12.2015

The new CC1310F128RGZT IC from Texas Instruments is a multi-core system-on-a-chip consisting of:

- high-performance microcontroller Cortex-M3 48 MHz;
- 433/868 MHz radio with its own Cortex-M0 core;
- nano-consuming sensor controller with a separate 16-bit core;
- power supply subsystems with built-in DC/DC converter.

The CC1310 Universal Radio supports virtually any proprietary protocol and is compatible with CC1101, CC430, CC100L, CC1120, CC1200 and more transceivers.

A unique feature of the CC1310 is its low current consumption. In continuous receive mode, the current consumption is 5,5 mA, which is several times better than many competing solutions. CC1310 allows you to create wireless sensors that can work up to 10 years from a disk element CR2032.

Features of CC1310:

Cortex-M3 Up to 48-MHz Clock Speed;
128KB Flash, 20KB of Ultralow Leakage SRAM;
Sub1GHz Software Defined Radio;
Range up to 20 km (-124 dBm @ 0,625 kbps ; +14 dBm);
Best in class power consumption (5,5 mA RX);
Consumption of 600 nA at RTC with preservation of all RAM-memory;
Compatible with CC1101, CC110L, CC430, CC112x, CC12xx;
Network protocols: 6LoWPAN, 802.15.4g;
EEMBC ULPBench Score: 158.

The new CC1310 system-on-a-chip is a representative of the new CC13xx/CC26xx platform that supports 5 different technologies based on a single internal chip architecture.

The unique platform includes several pin-compatible chips that support Bluetooth Smart, Sub1GHz, ZigBee, 6LoWPAN, IEEE 802.15.4, RF4CE and proprietary data transfer protocols at speeds up to 4 megabits per second.

The 2,4GHz and Sub1GHz chips are interchangeable in terms of pin matching. Additionally, the same processor and a completely matching set of peripherals are located inside, which allows the developer to easily change the frequency range or the wireless communication standard used without significant time spent on product redesign.
