Fusibili Fluidici – Sfruttare il ‘Fallimento Programmato’ per Garantire la Salute del Sistema

Fluidic fuses are the latest development in the programmed failure sector. These devices perform a task similar to the fuses in your home. When blown due to pressure, they can be rebonded and reset. In this way, they prevent damage from over-pressurization and provide a reusable option to the market. Here’s what you need to know.

Fallimento Programmato

The concept of programmed failure has intrigued engineers for decades. Fuses are a perfect example of programmed failure. They flip when a certain amount of current or short is detected. Their failure prevents greater damage to the electrical system. In this way, engineers can transform failure from a limitation into an advantage.

Programmed failures allow engineers to determine stress points and initiate automatic processes following their breach. The key to programmed failure is having a strong understanding of the device’s internal components and their exact failure steps.

Studio sui Fusibili Fluidici a Fallimento Programmato

A new study published in Cell Reports Physical Science called “Fallimento programmabile in dispositivi fluidici a foglio termosealable“¹  introduces the concept of fluidic fuses. These fuses work on pressure rather than current. If a pipe with one of these devices receives too much pressure, the fluidic fuse will pop based on predetermined thresholds, allowing for multiple use-case scenarios.

Fusibili Fluidici a Foglio

The core of the research is a new type of sheet-based fluidic fuse. These fuses utilize thin, flexible sheets of material specially bonded together to form an internal network. This network has fluid that will cause the fuse to separate at certain areas if the pressure exceeds the preset parameters.

Come Falliscono i Fusibili Fluidici

The fluidic fuses introduced by engineers in this study leverage a multi-bond approach. Each seal has a separate strength and pressure setting at which the bond will break. This setup allows the system to provide multiple safety indicators and initiate a multi-step process to prevent further failure based on current pressure conditions.

Tre Regimi di Guasto

The researchers identified three key failure phases linked to the thermal bonding process used in fabricating these fluidic fuses. The first phase occurs when bond strength increases as the bonding temperature rises. In the second phase, a plateau forms where the material itself dictates cohesive failure. The final phase involves overheating during fabrication, which weakens the material’s integrity and lowers its failure threshold.

L’adesione si riferisce al modo in cui i fusibili fluidici sono legati insieme. Più forte è il metodo di adesione, più pressione è necessaria per far guastare il fusibile. Gli ingegneri hanno anche osservato che la forma di ciascun fusibile fluidico influisce sulla sua capacità di gestire la pressione. Design più complessi erano più propensi a scoppiare a pressione più bassa, consentendo una regolazione precisa.

L’ultima preoccupazione era la performance d’impatto. Lo studio si è concentrato su un unico sistema di materiale e ha esaminato come diverse temperature di giunzione influenzino il comportamento di guasto. Piuttosto che testare più materiali, la ricerca si è focalizzata sull’ottimizzazione delle condizioni di giunzione termica per controllare il fallimento programmato. Inoltre, il materiale doveva essere in grado di gestire variazioni di temperatura.

Test del Fusibile Fluidico a Fallimento Programmato

The group tested their theory by creating multiple fluidic fuses. These devices underweight a variety of trials. Burst tests were used to find the exact pressure failure readings. Additionally, the adhesion underwent a series of T-peel tests to evaluate its strength.

The test results showed the fluidic fuses could limit damage due to over-pressurization in multiple systems. Additionally, the team noted the ability to initiate task sequences from a single pressure input.

For example, imagine a safety system opening switching inputs, notifying safety personnel, and opening exhaust valves automatically because overpressurization was detected. This type of sequencing is only the tip of the iceberg.

Benefici del Fusibile Fluidico a Fallimento Programmato

This research could lead to a plethora of benefits across multiple industries. For example, the soft robotics sector could leverage this tech to make non-compliant robots safer and smarter.

Another benefit of this study is that it provides a framework for further developments regarding fluidic fuses. These devices could be used to ensure pressurized systems are safer than ever. They are lightweight, affordable, and reusable. Additionally, they can be easily rebonded with minimal costs.

Attivatore

Another huge draw to fluidic fuses is their capability to act as a single input switch. Already, engineers have come up with multiple scenarios in which a fluid fuse can be strategically placed to sequence multiple tasks within a device or across a range of devices.

Futuro dei Fusibili Fluidici

In the future, fluidic fuses could be combined with IoT (Internet of Things) and AIoT technologies to provide real-time data to logistics firms and manufacturers. These systems could enable safer and more accurate pressure monitoring without driving up costs. As such, fluidic fuses will become smart, increasing the ability to communicate via the internet to larger systems in real time.

Several manufacturers could see major benefits from this study. For one, robotics firms could use this study to make soft robots safer and more agile. Leading soft robotic technology leaders are constantly on the lookout for breakthroughs that will improve their ROI and product capabilities. Here’s one company leading the soft robotics revolution.

Teradyne

Teradyne (TER ) entered the market in 1960 and has a main headquarters in MA. The Company was founded by Alexander V. d’Arbeloff and Nicholas DeWolf to provide reliable and accurate automatic test systems. Today, the company offers a wide range of testing systems, robotics, software, and wireless options.

Teradyne is a leader in soft robotics. It has demonstrated a pioneering spirit with its robotic arm products. The use of the fluidic fuses could help to improve this offering and a long list of other product’s performance and capabilities.

Currently, TER has a market cap of $20.2B. The company’s positioning and innovative efforts make this stock a strong “hold” for those seeking an established robotics option.

I Fusibili Fluidici a Fallimento Programmato Miglioreranno la Sicurezza

It would be hard to imagine a world without electric fuses. Devices would be blowing up regularly due to shorts and other issues. The same scenario goes for pressurized systems. The better the programmed failures safety mechanisms, the better it is for everyone. As such, you need to commend these engineers on opening the door for new levels of safety and beyond.
