# Male Pregnancy Simulations Takayuki Kosaka's 'Mommy Tummy' Will Show Men What Pregnancy Feels Like By Katie Jensen | Published 2011-08-19 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/mommy-tummy-suit-gives-men-baby-bumps References: [innovationnewsdaily](http://www.innovationnewsdaily.com/mommy-suit-pregnancy-siggraph-2011-2187/) & [siggraph.org](http://www.siggraph.org/s2011/content/mommy-tummy-pregnancy-experience-system-simulating-fetal-movement) For guys eager to pack on the pounds around the tummy and ta-tas, Takayuki Kosaka’s team from the Kanagawa Institute of Technology have just the trick: the [**Mommy Tummy**](http://www.siggraph.org/s2011/content/mommy-tummy-pregnancy-experience-system-simulating-fetal-movement) suit! It’s an interactive, torso-hugging top that [simulates pregnancy](https://www.trendhunter.com/trends/peanut) by allowing the user to feel the faux-fetus’s temperature, movement and heartbeat. It even allows the wearer to communicate with the fetus via belly-patting! Soft, rubbing movements elicit calm responses from the fetus, whereas quick, jerky movements cause the fetus to experience physical distress. After a few minutes of wearing, the Mommy Tummy’s belly and breasts will change in both size and shape, simulating growth over 9 months as the pregnancy comes to term. An auxiliary screen displays a 3-D model of the fetus and charts changes in mood and activity levels during development. To get that realistic feeling, Takayuki Kosaka’s team simulated two types of [fetal movement](https://www.trendhunter.com/trends/doola) -- kicking and wiggling -- using a technique adopted from Georg von Bekesy’s tactile funneling illusion. To put it simply, the wearer’s physical vibrations cause an electric stimulation in the suit-baby. The suit was revealed at **SIGGRAPH 2011**, a Vancouver conference that took place August 7th-11th, featuring 15,872 artists, research scientists, gaming experts and developers, filmmakers, students, and academics from 74 countries. Surprisingly, I don’t think we’ll be seeing it on the runways of [fall fashion week](https://www.trendhunter.com/trends/seraphine-1). But it might just make its way into the closets of some of the world’s more empathetic fathers-to-be. ## Trend Insights (Trend Hunter) - Score: 4.2/10 - Popularity: 34% | Activity: 85% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Science](https://www.trendhunter.com/science) ## Key Themes ### Why This Trend Is Growing - **Interactive Pregnancy Simulations:** Disruptive innovation opportunity: Develop more advanced and realistic pregnancy simulation suits to enhance empathy and understanding for expectant fathers. - **Virtual Fetal Communication:** Disruptive innovation opportunity: Create technologies that enable communication between parents and unborn babies, fostering a stronger bond during pregnancy. - **Wearable Technology for Pregnancy:** Disruptive innovation opportunity: Design wearable devices that provide real-time feedback on fetal development and enhance the overall pregnancy experience. ### Industries Being Reshaped - **Healthcare Technology:** Disruptive innovation opportunity: Develop advanced medical technologies that leverage virtual reality and haptic feedback to improve prenatal care and education. - **Parenting and Family Services:** Disruptive innovation opportunity: Create specialized services and products to support expectant fathers and enhance their involvement in the pregnancy journey. - **Fashion and Wearable Technology:** Disruptive innovation opportunity: Combine fashion and technology to create fashionable and functional pregnancy wear that enhances comfort and promotes empathy. ## Related on Trend Hunter - [Expecting Mother-Themed Burgers](https://www.trendhunter.com/trends/pregnancy-whopper.md) - [Prenatal Care Wearables](https://www.trendhunter.com/trends/morrama.md) - [Pregnancy-Friendly Fitness Equipment](https://www.trendhunter.com/trends/bala-mama.md) - [Sweat-Based Pregnancy Wearables](https://www.trendhunter.com/trends/molesense.md) - [Practical Dad-Friendly Hoodie Designs](https://www.trendhunter.com/trends/dad-hoodies.md) - [New Dad-Focused Apps](https://www.trendhunter.com/trends/dadtech.md) - [De-Stressing Wearable Massagers](https://www.trendhunter.com/trends/am1.md) - [Supportive Maternity Shapewear](https://www.trendhunter.com/trends/maternity-shapewear.md) - [Advanced Muscle-Toning Suits](https://www.trendhunter.com/trends/sweetmyo.md)
