Mindcandy: Going tiny

Use #Mindcandy as a strategic sensing engine to help leadership teams identify the signals they are missing. It fuels the strategic conversation about what is next. DM “SESSION” if you want to find out more.

The future is getting smaller. Much smaller.

We are obsessed with bigger AI models, massive data centres, and increasingly powerful computers. Meanwhile, another revolution is happening at the opposite end of the scale. Sensors are becoming almost invisible. Computing is moving into materials. Intelligence is getting embedded in the physical world. Three developments illustrate the shift.

  1. Muscles that communicate with machines. MIT researchers have demonstrated how tiny magnetic beads implanted in muscles can accurately track movement, potentially enabling amputees to control prosthetic limbs more naturally. Read more.
  2. Butterflies are becoming data sources. Engineers have created solar-powered tracking devices weighing approximately as much as a grain of rice. Scientists can now follow individual butterflies across migration routes, revealing previously invisible ecological patterns. Read more.
  3. Electronics that remember. German researchers have developed a nanoscale electronic component capable of switching, storing, and remembering electrical activity. It is an early step towards brain-inspired computing that combines processing and memory in the same hardware. Read more.

The strategic implication

Miniaturisation changes everything. When sensing, computing, and potentially learning can happen almost anywhere, the boundaries between biology, hardware, and intelligence begin to dissolve. Imagine products that monitor themselves, materials that respond to their environment, infrastructure that detects its own weaknesses, and medical devices that continuously adapt to their users. The next wave of digital transformation might be almost invisible.

The future fitness move

Small technology. Enormous strategic consequences. Explore the convergence of miniaturisation, sensors, materials science and AI. Identify three things in your business that are currently impossible, expensive or difficult to measure. Then imagine what becomes possible when those constraints disappear.

Solar Panels Are Now Producing So Much Power That They’re Leaving Nuclear Plants in the Dust

According to new reporting by the BBC, photovoltaics will account for 10 percent of the world’s power generation by the end of 2026, a threshold which will see solar energy officially surpass nuclear fission.

Startup taps underwater volcano as energy source in “proof point” test

The world’s first demonstration of a subsea geothermal power plant has taken place near an active underwater volcano almost a mile below the ocean surface. It generated less than 10 seconds of net-positive electricity but showed the technical feasibility of tapping another form of renewable energy underwater.

US team develops device that powers battery-free sensors for at least 24 hours

U.S. researchers have created a graphene-based device that harvests energy from ambient radiation. It provides the electricity needed to operate an ultra-low-power temperature sensor. The technology lets the sensor keep operating for at least 24 hours during a power outage.

The next digital twin isn’t of a machine, it’s of your business

Digital twins already model machines, but a twin of your business that shows what each process is actually worth could change how you decide where to invest.

Armored caterpillars offer robot designers lessons in crossing slippery glass

Animals have long been one of the primary sources of inspiration for robotics researchers. This is because they rely on sophisticated biological mechanisms and locomotion strategies that could be artificially reproduced in robots to equip them with desired capabilities.
