Senso

18/09/2026

Senso was co-developed alongside Deaf Communities across more than eight countries. Years of focus groups helped us create a solution grounded in the real needs and lived experiences of real people.

As we approach product launch, we’re hosting virtual demonstrations for those who contributed to our journey and those discovering Senso for the first time.

So, to book a session to experience how Senso makes important sounds accessible through vibrations and LED lights. Please schedule an appointment with us here:

Background...Discover how SENSO monitors everyday sounds such as alarms, door knocks and baby cries. These sounds are felt through smooth vibrations, while colour-coded LED lights give indication of where the sound comes from.Demo is open to individuals, families, schools, employers, potential

Senso is entering the final stretch of its journey towards getting this all impactful solution to the wrists that need it most.

We’re grateful to have had Shell and Shell LiveWIRE walking this important last mile with us, supporting our efforts to turn years of co-creation, testing and perseverance into real-world impact.

One step closer to safer, more independent and inclusive communities. 💙

LED lights are a full on function and feature of SENSO, a non intrusive wrist wearable sound assistive co-designed with Deaf Communities to feel sounds through vibrations and LED lights... While developing and prototyping SENSO and working on LED selections and refinements, here is some timeline about LED's that we came across and thought, LED lights just have to work with SENSO and due to the type of technical capability in the team, LED worked:
1. In 1907, British experimenter in Marconi labs Henry Joseph Round noticed for the first time that when an electrical charge of 10volts is applied to silicon carbide crystal, it emits yellowish light
2. However, the first to investigate it and to propose a working theory was Oleg Vladimirovich Losev from Russia, who published a paper called “Luminous carborundum detector and detection effect and oscillations with crystals“ in 1927
3. In 1961, Gary Pittman and Bob Biard from Texas Instruments found that that gallium-arsenide diode emits infrared light every time it is connected to current. The same year they received patent for infrared LED.
4. In 1962, Nick Holonyak Jr, an employee at General Electric, developed first light-emitting diode that emitted light in the visible part of the frequency range. It was a red LED.
5. In 1972, M. George Craford, who was a graduate student of Holonyak, invented the first yellow LED and a brighter red LED.
6. In 1976 Thomas P. Pearsall developed high brightness light-emitting diode, for use with fiber optics in telecommunications.
7. In 1979 Shuji Nakamura of Nichia Corporation made first blue LED but it was too expensive for commercial use until 1994.

We're back.

It's been years since our last post. Years of building, testing, learning, and refusing to give up on a vision we believe can change lives.

Today, we're excited to say that Senso is entering a new chapter.
After all this time, we're finally getting ready to...

LAUNCH.

Thank you for being part of this journey. More updates coming soon. 🚀

Today, on the 23rd of September, we celebrate the International Day of Sign Languages, a day dedicated to raising awareness about the importance of sign language in ensuring the human rights of Deaf Communities.

However, it’s disheartening to acknowledge that in 2024, only four countries in Africa, which are South Africa, Kenya, Zimbabwe, and Uganda actually recognize Sign Language as an official language.

With 45 countries on this continent, it’s a shame that such a vital native language for Deaf individuals remains under-recognized in most nations. There's still a long way to go in achieving inclusivity for all.

If you speak, talk, write, present, or educate about accessibility and disability inclusion in any digital format (think about this for a moment in today's world)....

Use alt-text for your images

Refrain from emoji extravaganzas

Provide accurate and usable captions

Know what closed captions are and are not

Use CamelCase hashtags so they are readable (CapitalizeTheFirstLetterOfEachWordEvenIfThatReallyIsPascal)

Use headers for structure in your documents and communications

Make sure your documents and presentations are accessible for people who use assistive technologies.

If you speak, talk, write, present, or educate about accessibility in any digital format do these things.

If you have not yet, today's a great day to start.

Pick one or two and commit to making this HOW you communicate ALWAYS.

Make a date/time to add one or two more and commit to making these HOW you communicate ALWAYS.

Accessibility includes accessible communications.
Accessibility means inclusive communications.

Late last year, RedBull TV invited us to be a part of their series "Walk a mile in my shoes", we always appreciate an opportunity to tell a glimpse of our journey and for that, we appreciate the RedBull team for this. Please see the link to see what this episode entailed, please let us know should you have any issue with the subtitles, enjoy-:)...

Zuko Mandlakazi shares how he created the Senso wristband to help the deaf community with their surroundings.

How it started VS How it's going... Disclaimer: since we aren't able to share a complete product, the one ready for manufacturing, the product assembled on the right is the prototype reiteration we did in April 2019. We just couldn't resist this challenge🤟

GSM Association, an industry organisation that represents the interests of mobile network operators worldwide ran a study on assistive devices from Africa. Senso was amongst these African companies that participated, representing South Africa. An honour for us being a part of this great body of work. Please view the study on the link below when you can.
