Multi-Sensory Feedback Systems

Sensory feedback is not a “nice-to-have”. If it doesn’t stay on the skin, it doesn’t exist. This Scientific Reports paper “Ultra-conformable tattoo electrodes for providing sensory feedback via transcutaneous electrical nerve stimulation” tackles a very practical bottleneck in non-invasive neurostimulation: standard wet Ag/AgCl electrodes don’t adapt well to irregular residual-limb surfaces and can detach during movement. :contentReference Their proposal is elegant: ultra-conformable, Paryylene C–based “tattoo” electrodes to deliver somatotopic sensations via TENS, without surgery. :contentReference. A few details: • impedance stability over a working-day window: max variation ~8% over 9 hours at the target stimulation frequency :contentReference; • comparison on 12 participants: no significant differences vs wet Ag/AgCl in rheobase (p>0.3) and chronaxie (p>0.15), and comparable sensory perceptions :contentReference; • lower operational impedance with tattoo electrodes (practical advantage for real use) :contentReference. It’s about making non-invasive sensory feedback less fragile and more wearable, the kind of detail that determines whether feedback can live outside the lab. 📝 Link in the first comment. Question for those working with stimulation/wearables: what is the real blocker for daily-life TENS feedback today: adhesion, selectivity, skin comfort, or long-term stability? #haptics #sensoryfeedback #tens #transcutaneousstimulation #neuroprosthetics #prosthetics #upperlimbprosthesis #somatosensory #somatotopy #wearables #epidermalelectronics #electrodes #tattooelectrodes #parylenec #biomedicalengineering #rehabilitation #assistivetechnology #humanmachineinterface #embodiment #neuroengineering

𝗕𝗶𝗼𝗲𝗹𝗮𝘀𝘁𝗶𝗰 𝘀𝘁𝗮𝘁𝗲 𝗿𝗲𝗰𝗼𝘃𝗲𝗿𝘆 𝗳𝗼𝗿 𝗵𝗮𝗽𝘁𝗶𝗰 𝘀𝗲𝗻𝘀𝗼𝗿𝘆 𝘀𝘂𝗯𝘀𝘁𝗶𝘁𝘂𝘁𝗶𝗼𝗻 The rich set of mechanoreceptors found in human skin offers a versatile engineering interface for transmitting information and eliciting perceptions, potentially serving a broad range of applications in patient care and other important industries. Targeted multisensory engagement of these afferent units, however, faces persistent challenges, especially for wearable, programmable systems that need to operate adaptively across the body. Here the authors present a miniaturized electromechanical structure that, when combined with skin as an elastic, energy-storing element, supports bistable, self-sensing modes of deformation. Targeting specific classes of mechanoreceptors as the basis for distinct, programmed sensory responses, this haptic unit can deliver both dynamic and static stimuli, directed as either normal or shear forces. Systematic experimental and theoretical studies establish foundational principles and practical criteria for low-energy operation across natural anatomical variations in the mechanical properties of human skin. A wireless, skin-conformable haptic interface, integrating an array of these bistable transducers, serves as a high-density channel capable of rendering input from smartphone-based 3D scanning and inertial sensors. Demonstrations of this system include sensory substitution designed to improve the quality of life for patients with visual and proprioceptive impairments. https://lnkd.in/gDbGj2zC

𝗧𝗵𝗲 𝗔𝗻𝗮𝗹𝗼𝗴𝘆: 𝗪𝗵𝗲𝗻 𝗦𝗶𝗹𝗲𝗻𝗰𝗲 𝗜𝘀 𝗮 𝗦𝗶𝗴𝗻𝗮𝗹 In aviation, the black box records everything—data, audio, pressure changes—so investigators can understand not just what happened, but why. In healthcare, we have patient surveys. Complaint reports. Staff notes. But let’s be honest: most of the experience data we gather is either delayed, sanitized, or incomplete. 𝗪𝗵𝗮𝘁 𝗶𝗳 𝗼𝘂𝗿 𝗵𝗼𝘀𝗽𝗶𝘁𝗮𝗹𝘀 𝗵𝗮𝗱 𝗮 “𝗯𝗹𝗮𝗰𝗸 𝗯𝗼𝘅” 𝗳𝗼𝗿 𝗽𝗮𝘁𝗶𝗲𝗻𝘁 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲? A real-time, multi-sensory, always-on record of what patients go through, beyond what they tell us in a form? 𝗧𝗵𝗲 𝗚𝗮𝗽𝘀 𝗪𝗲 𝗗𝗼𝗻'𝘁 𝗧𝗮𝗹𝗸 𝗔𝗯𝗼𝘂𝘁 We assume feedback = reality. But here’s what we may be missing: • Patients who never speak up: due to fear, cultural norms, or low expectations • Body language in waiting rooms or during discharge conversations • Non-verbal drop-offs: appointment no-shows, cancelled follow-ups, or early discharges • Tone and emotion in call center interactions rarely captured or analyzed • “Too late” feedback: Post-discharge surveys don’t help today’s patient 𝗧𝗵𝗶𝗻𝗸 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁𝗹𝘆: 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝗦𝗲𝗻𝘀𝗶𝗻𝗴 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸 To create a true PX Black Box, we need to blend different modes to unlock different insights - Passive Signals: No-shows, long wait room times, silent exits - Emotional distress, friction, avoidance - Environmental Cues: Noise levels, seating patterns, eye contact - Discomfort, safety perception - Behavioral Feedback: Staff-patient micro-interactions - Empathy, tone, relational experience - Active Listening: Surveys, complaints, social media, interviews - Verbalized perceptions and emotions 𝗥𝗲𝗮𝗹-𝗪𝗼𝗿𝗹𝗱 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 • Use AI sentiment analysis on call recordings & WhatsApp messages • Create a “𝙋𝙓 𝙎𝙝𝙖𝙙𝙤𝙬𝙞𝙣𝙜 𝙋𝙧𝙤𝙜𝙧𝙖𝙢” where staff silently observe journeys end-to-end • Equip waiting areas with PX Observers who map emotion, not just time • Integrate “𝙎𝙞𝙡𝙚𝙣𝙩 𝙀𝙭𝙞𝙩 𝙄𝙣𝙩𝙚𝙧𝙫𝙞𝙚𝙬𝙨” via digital kiosks no names, no pressure • Correlate EHR behavior patterns with patient satisfaction dips 𝗬𝗼𝘂𝗿 𝗣𝗫 𝗟𝗮𝗯 𝗘𝘅𝗲𝗿𝗰𝗶𝘀𝗲 Reflect on these 3 questions as a Leader or PX Leader: 1. What patient experiences in my hospital are invisible to our current systems? 2. How often do we act on what’s not said rather than what’s measured? 3. What could we learn by simply observing one full patient journey in silence? 𝗙𝗶𝗻𝗮𝗹 𝗧𝗵𝗼𝘂𝗴𝗵𝘁 Experience is not just data it’s signals.

What if your next strategy session 𝘴𝘮𝘦𝘭𝘭𝘦𝘥 like success? Neuroscience says it might just help it stick. A client recently had a graphic artist capture one of my strategy trainings. Looking at this visual feast got me thinking: what about the other senses? Turns out there's solid science here: multisensory experiences create stronger neural pathways for shared understanding. Work environments that engage multiple senses show 30% higher engagement. And when we move, we form more durable memories. I'm not suggesting we turn meetings into a carnival of sensory experiences. But my most successful facilitations already tap more senses than I realized: 𝗠𝗼𝘃𝗲𝗺𝗲𝗻𝘁: We vote with our feet, grouping in corners to show our stance. 𝗦𝗼𝘂𝗻𝗱: We play customer interview clips to keep real voices in the room. 𝗧𝗼𝘂𝗰𝗵: Participants sketch (however badly) their target customer, forcing clarity and prioritization. 𝗦𝗺𝗲𝗹𝗹: Yes, I've used Mr. Sketch markers. No proof it helps, but it does get noticed. 𝗧𝗮𝘀𝘁𝗲: Well-fed teams make better decisions. (Strategic snacking?) Could we push this further without getting weird about it? Ideas: • 𝗥𝗼𝗹𝗲 𝗥𝗼𝘁𝗮𝘁𝗶𝗼𝗻 𝗦𝘁𝗮𝘁𝗶𝗼𝗻𝘀: Physical stations around the room where teams embody different perspectives (customer, competitor, regulator). • 𝗧𝗶𝗺𝗲𝗹𝗶𝗻𝗲 𝗪𝗮𝗹𝗸𝗶𝗻𝗴: Laying out the strategic timeline on the floor and having executives literally walk through their company's future, stopping at key milestones to discuss what needs to happen. • 𝗕𝘂𝗶𝗹𝗱 𝗬𝗼𝘂𝗿 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗠𝗼𝗱𝗲𝗹: Using blocks to physically construct how value flows through the organization. I’d love to hear from you: What sensory elements have you incorporated into strategic discussions, intentionally or accidentally? What worked? What flopped?

China has developed an advanced electronic skin that allows humanoid robots to sense pressure, temperature, and physical damage—enabling reactions similar to human pain responses. This breakthrough significantly enhances robotic awareness, safety, and interaction capability. The electronic skin is composed of flexible layers embedded with thousands of sensors that detect touch, force, heat, and sharp impacts. When excessive pressure or damage is detected, signals are instantly sent to the robot’s control system, triggering reflex-like reactions such as pulling away or adjusting grip strength. Pain perception in robots is not about suffering but protection. By detecting harmful conditions early, robots can prevent self-damage, handle fragile objects more carefully, and operate safely alongside humans. This is especially critical for robots used in healthcare, manufacturing, and public environments. The technology also improves learning. Feedback from the electronic skin allows robots to refine movements over time, similar to how humans learn through sensory experience. This results in better precision, adaptability, and durability. This development represents a step toward robots that are not just intelligent, but physically aware. As humanoid robots become more integrated into society, such sensory systems will be essential for safe and effective human-robot collaboration.

Preclinical research has long struggled with reproducibility, a problem that costs an estimated $28 billion annually in the U.S. alone. Enter multisensor home cage monitoring systems, a technological leap forward that might just be the key to solving this crisis. 📝 What makes multisensor systems so powerful? 🔎 They integrate capacitive sensing, video analytics, RFID tracking, and thermal imaging to monitor animal behavior and physiology continuously, non-invasively and directly in the animals’ home environment. Damien Huzard, PhD 🔎 Unlike single-sensor systems, they cross-validate data streams. 🔎 They overcome common hurdles in animal research: from lighting challenges in video tracking to individual tracking in group-housed settings, all while minimizing stress-induced artifacts. ⚠️ Why this matters: Traditional approaches miss subtle circadian patterns and rely on intrusive testing. Multisensor systems, by contrast, detect nuanced shifts in activity and physiology, early indicators of disease progression or treatment effects that single-sensor systems often miss. 🔎 The payoff: By combining these complementary sensors, researchers gain unparalleled accuracy and reliability in their data. This precision is essential for aging studies, chronic disease models, and drug development, where small changes over time can make or break scientific insights. 💬 Have you tried multisensor monitoring in your work? What challenges did it help you overcome? ♻️ Share this post to highlight a powerful tool for boosting reproducibility in animal studies! #PreclinicalResearch #DigitalBiomarkers #AnimalWelfare #LabInnovation #ResearchIntegrity #MultisensorMonitoring #OpenScience
